X-Rite Optix XR and Monaco EZColor Work With 64-bit Windows 7

by Alan Haynes / PhotoCitizen on April 26, 2010

You just installed the 64-bit edition of Windows 7. Now,  you want to calibrate your monitor. But your ancient Optix-XR color calibrator and Monaco EZColor software won’t install. Looks like you need to spend a couple hundred bucks more on new color calibration equipment. Or do you?

You may also be interested in my article, “Monaco EZ Color and Optix-XR Works with Windows Vista and a New Driver.”

Monaco EZColor 2.6.5 and Optix XR DTP94 DO work with Windows 7 64-bit.

Persistence Pays Off

If you call X-Rite technical support, you’ll be told flat out that the Optix XR will not work with the 64-bit version of Windows 7. If you visit their website, you’ll be given a glimmer of hope, but no real solution. I didn’t try the workaround mentioned there because it’s not necessary.

I’ve personally used the method I describe below to successfully install the Optix XR and EZColor on computers running Windows 7 Home Premium (64-bit and 32-bit versions) and 32-bit Windows Vista. I’ve been told that it also works on the 64-bit version of Windows 7 Professional. So, no matter which version of Windows 7 or Windows Vista you use, the truth is the X-Rite Optix XR and Monaco EZColor 2.6.5 software will work.

Note: the software downloads mentioned here are free, but in order to use the latest version of EZColor (version 2.6.5), you’ll need your serial number from that version or from your old version 2.5 of EZColor.

How Not to Install the Optix XR Driver

Installing the Optix XR driver and the EZcolor software will be pretty straight-forward for anyone with a new computer running Windows 7. And, if you’ve upgraded your old machine to Windows 7 by using Windows 7’s Custom (advanced) option where your old hard drive is wiped clean before Windows 7 is installed, it should be just as easy.

In my case, I upgraded from Windows Vista using the upgrade option in Windows 7’s installer. That option leaves all of your old files and programs in place which  saves a lot of time,  but introduces a few problems of its own. More about this later.

Because of a few upgrade-related problems, I spent hours installing the Optix XR and EZColor software on my computer, so before I tell you how to succeed in installing the Optix XR driver, let me show you a few ways to fail. You may have better luck.

Optix XR Installation: Device driver software was no successfully installed. Strike 1: driver install failed

The obvious first step was to plug the Optix XR DTP94 into a USB port on my new Windows 7 machine. Obvious, but flawed. Windows 7 attempts to locate the correct driver and, after a few seconds, it reports that the “Device driver software was not successfully installed.” Strike one.

Optix XR DTP-94 in Windows 7 Device Manager Strike 2: Device Manager

Strike two: I went to Windows’ Device Manager. (In the Control Panel, choose Hardware and Sound, then under the Devices and Printers section, choose Device Manager.) There I found the device called X-Rite DTP94 under the Other Devices section with a big yellow exclamation mark next to it indicating it was not functioning properly. I right-clicked on X-Rite DTP94 and chose Update Driver Software. Then I chose Search Automatically for Updated Driver Software. It didn’t find any, so it failed again.

Windows found driver software for you device but encountered an error while attempting to install it. X-Rite DTP94 Strike 3: Failed again

Finally, I went back to the Device Manager, uninstalled the X-Rite DTP94, and told it to Scan for Hardware Changes (or you could just restart the computer). It found the DTP94, but again failed to install any driver for it. Strike three – I’m outta here!

Step-by-Step: Installing the Optix-XR Hardware

Follow these instructions to get your Optix XR DTP94 and EZColor software to work with 64-bit Windows 7:

    1. Start by downloading the correct driver software from the X-Rite website. It’s called “Unified 32 & 64-Bit Drivers, 98, 2000, XP, & Vista, version″ dated 1/10/2007. The actual file name isX-RiteUSB_v3100.zip. Click the link to go to X-Rite’s website to get the file. Click on the words PC Version to start the download. Save it to the Downloads folder on your computer (or any other convenient spot).
Unzipping Optix XR driver software Extract X-RiteUSB_v3100.zip
    1. Once, the file is downloaded, navigate to the Downloads folder and unzip it by right-clicking on X-RiteUSB_v3100.zip and choosing Extract All… from the pop-up menu. Another window will pop-up asking you where you want to save the extracted folder. Leave it at its default which will place it in the same folder as the original zipped file. Make sure you place a check mark in the box next to Show extracted files when complete. This will make it easier to find the extracted files later. Click on Extract.
    2. Next, you may see a window that says, “Do you want to copy this folder without encryption? A problem has prevented this folder from being encrypted.” I’m not sure why this comes up, but the folder does not need to be encrypted, so click Yes to make it go away and continue with the extraction. If you don’t see the encryption message, carry on with the next step.
    3. Now, plug the DTP94 into one of your USB ports. With luck, your computer will notify you – via a pop-up balloon at the lower right of your screen that it is “Installing Device Driver software.” With even more luck, after a few seconds, another balloon message will inform you, “X-Rite DTP94 Device driver software installed successfully.” If you see that message, you’re done with the Optix XR hardware installation and can move on to installing the EZcolor software. My laptop, running a fresh installation of the 32-bit version of Windows 7 successfully installed the driver. My upgraded 64-bit desktop machine did not.
    4. If you don’t see the “driver software installed successfully” message, you have some more work to do. Go to Windows’ Device Manager as explained above.
    5. Once you’re in the Device Manager, you’ll find X-Rite DTP94 in the Other Devices section. It will have an icon next to it showing an exclamation point on a yellow background. That icon indicates the device is not working (remember, the driver was not found when we tried to install it earlier.)
Update driver software for X-Rite DTP94 in Windows 7 Device Manger Update driver software
    1. Right-click on X-Rite DTP94 and, from the pop-up menu that appears, choose Update Driver Software.
    2. Click on Browse my computer for driver software.
    3. Browse to the folder where you unzipped the downloaded driver file. This would normally be in your Downloads folder. There, you should find a folder called X-RiteUSB_v3100. Click once on that. You don’t have to dig any deeper into that folder even though there is another subfolder within the X-RiteUSB_v3100 folder. Just click once on X-RiteUSB_v3100 to highlight it and click OK.
Browse for software driver on your computer and include subfolders Browse for driver
    1. Now you’re back in the window called Browse your computer for driver software. Make sure there is a check-mark in the box next to Include subfolders, then click the Next button.
    2. Windows will tell you that it is “Installing driver software.”
    3. You’ll probably immediately get another pop-up box warning you that “Windows can’t verify the publisher of this driver software.” Ignore the warning and click on Install this driver software anyway. If you don’t see this warning, continue with the next step.
Optix XR DTP94 driver updated successfully. Now you're done with the hardware. Update successful
  1. Now, installation continues and, in a minute or so, you’ll see “Windows has successfully updated your driver software.”
  2. Click Close and you’re done. Now it’s time to install the EZColor software.

Step-by-Step: Install Monaco EZColor 2.6.5 Software

The Monaco EZColor software is just as easy to install as the Optix XR driver. With my upgraded computer, I ran into a bit of trouble unrelated to the EZcolor software which I’ll explain below. For you, with your shiny new machine, it should go like this:

    1. Download EZColor 2.6.5 from the X-Rite website using this link: EZColor265.exe. Click on the words PC Version to start the download.
    2. Once the download completes, double-click on EZColor265.exe and you’ll probably get a Windows Security Warning asking you, “Are you sure you want to run this software.” Yes you are, so click on Run.
    3. Now, you’ll get a WinZip Self-Extractor window telling you that it will extract files to a folder called C:\EZ265. Click OK.
    4. Next, another WinZip window pops up. Don’t change anything, just click the Unzip button.
    5. The files will be unpacked and in a few seconds, you’ll see a window telling you that “175 file(s) unzipped successfully.” Click OK.
    6. Now, a Notepad window will open with six instructions telling you how to proceed. But that’s my job, so close that window and any other windows you have open.
    7. We need to navigate to the new EZ265 folder on our C: drive. From the Windows Start button, click on Computer. Next, double-click on your C: drive and you’ll see the EZ265 folder.
Double-click on setup.exe to start the EZColor 2.6.5  installation Setup.exe
    1. Open the EZ265 folder, then open the Installer subfolder, and you’ll see several files listed.
    2. Double-click on setup.exe. There are five files that begin with the word setup, so if your computer doesn’t show the suffix (the .exe), make sure you find the right one. You’re looking for an Application file with the file description, setup.exe. Hover your mouse pointer for a second over each of the setup files until you find it.
    3. Choose your preferred language and click Next.
    4. You’ll eventually see a window welcoming you to the Installshield Wizard. Click Next.
    5. On the ReadMe window, click Next again.
    6. You’ll have to agree to the software license by clicking Yes.
Enter your name and serial number in the Customer Information window Customer information
  1. Now, we’re at the Customer Information window. Here you’ll type in your User Name, Company Name and Serial Number. Enter anything you like in the first two fields, but make sure you type your old EZColor serial number in the last one. Then click Next.
  2. Now you’ll be asked to “Choose Destination Location”. Don’t change anything, just click Next.
  3. You’ll be asked to “Select Program Folder.” Leave it alone. Click Next.
  4. Finally, the software will begin to install and you’ll see the Setup Status window. After a minute or so, that window will be replaced by a window telling you, “Installshield Wizard Complete.”
  5. Click Finish and you’re done.

Calibrate Your Monitor

You'll find the EZColor folder in the All Programs section of the start menu X-Rite folder in the Start menu

To use the software, plug in your Optix-XR colorimeter and, in your Windows Start Menu, go to All Programs. Find the new X-Rite folder, open that up and click on EZcolor 2.6.5. The program starts and works the same way as it did in Windows XP and Windows Vista.

Monitor calibration works beautifully, but I haven’t tried to calibrate a scanner or printer with EZColor, so I’m not sure if it will work for those devices.

If you need a printer profile, you should download one for free from the manufacturer of your paper or your printer. Otherwise, have a custom profile made by someone who owns, and knows how to use, a spectrophotometer. It will be much more accurate than anything you can make at home with EZColor. I have mine made for $40 each by John Watts at Watts Digital Imaging. It’s money well-spent.

Odd Behavior

Your installation will probably go smoothly. If it does, you can skip this section. But I ran into a few oddities that I’ll share with you in case something similar happens to you.

If you have upgraded your computer to Windows 7 from an older version of Windows (XP or Vista), you may need to uninstall your old copy of EZColor 2.6.5 and reinstall it. The same thing with any old Optix XR driver. First, try following my instructions above. If that doesn’t work, then uninstall the old stuff and try again.

To uninstall EZcolor, go to your Control Panel and, under the heading Programs, you’ll see a link to Uninstall a program. Click that and wait a minute or so while Windows lists all the programs loaded on your computer. Then, scroll down until you find EZColor 2.6.5. Right-click it and choose Uninstall from the pop-up menu. Another window will pop up to give you a second chance to change your mind. Click its Uninstall button and, once the uninstall is done, click Finish.

To uninstall an old Optix XR driver, plug your Optix XR DTP94 into a USB port. Go to the Device Manager as explained above. Right click on X-Rite DTP94 and on the pop-up menu, choose Uninstall. The next window asks you to confirm your choice. On that window, there is also a check box next to the words Delete the driver software for this device.  Click on it to place a check mark in the box and then click OK. The device and its driver software will be uninstalled. Now, your machine has no trace of the old software. A new installation should work.

I ran into one other oddity when installing the EZColor software. It’s doubtful that you’ll experience the same problem, but just in case, here it is.

Setup has experienced and error. Error Code -6001. Error -6001

I got an error message in a pop-up window with the title InstallShield Wizard. It said that “Setup has experienced an error.” Then it mentions a few things I should do before re-running setup. At the bottom, it says, “Error Code -6001.” It turns out that error is related to the InstallShield software that many manufacturers, including Monaco, use to make their software simple to install.

The trouble has to do with an old version of the InstallShield software that was still on my upgraded computer. I had to remove an old folder from my computer to fix it. Here’s how:

Go to C:\Program Files (x86)Common Files\Installshield\Professional\Runtime and rename the folder called "10" to "10_orig" or just delete it. Rename or delete the “10” folder
  1. Navigate to the InstallShield folder at C:\Program Files (x86)\Common Files\InstallShield\Professional\RunTime. The easiest way to get there is to click on Computer in your start menu. Then copy the text I just mentioned (from C: to RunTime) and paste it into the field at the top of the Computer windows where it now says >Computer>. Hit your keyboard’s Enter key and you’ll be at the right spot.
  2. You’ll see a folder with the name, 10. Depending on which other versions of InstallShield you’ve used over the years, you may also see folders named 9 and 11. Delete the 10 folder (or just rename it to 10_original, if you’re afraid to delete it).
  3. Now, you can try installing the EZColor software again and it should work – you won’t see the Error 6001 again.

What If It Still Doesn’t Work?

I can’t guarantee that these methods will work for everyone. So, if you’ve followed my instructions, but it still doesn’t work, you have a couple of alternatives.

You don’t have to install the EZColor software. A company called Integrated Color Corporation makes an up-to-date replacement called ColorEyes Display Pro. I haven’t tried it, but it has received several glowing recommendations. You can buy it for $175, but they offer a free 10-day trial here. They say it works with the DTP94, so you won’t need to buy any new hardware.

The other option is to buy a whole new color calibration system. I’ve checked into these things and I’d buy the X-Rite i1 Display Pro for about $250. (Although some places use the term “Eye One,” the correct name according to X-Rite is “i1.”)   Although it is no longer in production, you may still be able to find the less expensive, but fully capable X-Rite i1 Display 2 for about $150.

If you also want to create your own printer profiles, the only accurate way to do it is with a full-blown spectrophotometer. The X-Rite ColorMunki Photo calibrates monitors, printers and projectors.

If you’re mad at X-Rite for not supporting your old Optix-XR, you can try one of DataColor’s Spyder 3 products.

I have just upgraded from Windows XP to Windows 7 (64bits)

I was running Xrite Monaco EZ Color so I followed the instructions on this site.

Sorry to say it would not work

Has anyone any suggestions please

2 Alan Haynes / PhotoCitizen June 26, 2010 at 7:13 am


Unfortunately, this fix does not work for everyone. Where did it fail for you?

You say you upgraded to Windows 7: do you mean you installed Windows 7 over Windows XP? Did you use the Advanced option for the upgrade?

Or did you upgrade to a whole new computer running Windows 7? With more details, maybe we can figure this out for you.


3 Leo July 15, 2010 at 11:44 am


First of all thank you for writing this article and offering users a possible solution. And I do hope readers drop posts informing you all went well.

Unfortunately it did not work for me either. I’ve used your Optix XR manual and ended at step 11 with the message “no access to file”.

First I checked my user’s rights to this folder (all users, full control) so that wasn’t the problem. Then I deleted all and downloaded again but with the same results.

I have upgraded my pc running Windows XP Prof. (32-bit) to Windows-7 Ultimate (32-bit) and used “clean install” in order to delete all files and programs. I use the X-Rite DTP94B dated January 2006.

I would appreciate your suggestion to help me solve this.

Kind regards from the Netherlands,

4 Leo July 15, 2010 at 1:10 pm

Back again,

Just to inform you I’ve solved this problem myself and you may delete my previous post. Perhaps you’ll find my solution helpful so I’ve written it hereafter, although, nothing special…
At least my search for fixing this problem has led me to your very informative site so I’ll drop by regularly!

The Windows-7 Ultimate software has the option to run a ‘compatibility wizard’ in order to use old Windows (XP) software.

First, I installed the software for Windows XP that came with the DTP94B (ColorNavigator CE)

Then I right clicked the new icon on my desktop in order to start the wizard. In my case I had to check the boxes for ‘program worked under XP’ + ‘using Service Pack-3’ + ‘user’s rights problems’.

After this I was able to run the software ColorNavigator CE that activates and uses the DTP94B.
I did NOT have to manually update the driver for this device. Before installing the software, Windows-7 had already informed me that no drivers were available.

After closing the program, Windows asked to confirm that the problem was solved and then saved the settings for future use.

5 Alan Haynes / PhotoCitizen July 19, 2010 at 7:05 am

Hello Leo,

I’m glad you found another solution and got your color calibration working. I had forgotten about the compatibility modes built into Windows 7. Sounds like you’re back in business. Thanks for the tip.


6 Bob August 12, 2010 at 4:01 pm


My wife has an old calibrator as well and ran across this site after we had problems getting the software and drivers installed on the Windows 7 64 bit machine.

We tried what you have outlined, but kept getting an ‘Access Denied’ error while trying to update the drivers.

It turns out that the drivers are encrypted. You mentioned in your step by step that the files do not need to be encrypted. Unfortunately, the option to decrypt the files on the extraction never appeared when I tried to extract the files (my wife downloaded 3 copies of the zip and none of the extractions offered the un-encrypt option).

I solved this by right clicking on the drivers folder and each of the files inside the driver folder (besides the pdf) and selecting ‘Unblock’ on the general tab, and de-selecting the ‘Encrypt contents to secure data’ option under the Advanced option of the general tab.

Of note: I had changed the compatibility options before trying this and did not change them back after I got the drivers installed.

Everything works fine.

Thanks for sharing this!

7 Doug August 13, 2010 at 6:02 am


I have Windows 7 Pro. So far my problem is that windows doesn’t recognize the optix hardware and puts it under other devices | Unknown device. Then when I try to update the driver with the downloaded (and unencrypted) file, there is a pop-up saing “Windows was unable to install your Unknown Device”

I did install the Monaco optix software –windows didn’t complain about it being incompatible, but it couldn’t find the hardware (obviously, because it’s not installed yet).

Any suggestions?

Thank you for dedicating a page to the Monaco problem!

8 Alan Haynes / PhotoCitizen August 13, 2010 at 2:54 pm

Hi Bob,

When I try to extract the files, I get a window that pops up with the title, “Confirm Encryption Loss” which asks me if I want to extract the files without encryption. There are two buttons: Yes and No. I guess you never got that window for some reason. Glad you got around it and thanks for sharing your solution.

Another way to extract these files and avoid the encryption problem is to use a third-party extraction program. WinZip is a popular one, but I use a free program called “7Zip.” I tried it just now on the Xrite driver folder and it unzipped the file with no problem. Here’s a link to the 7-Zip software: 7-Zip.org.


9 Alan Haynes / PhotoCitizen August 13, 2010 at 3:01 pm


You say you installed the Optix software, but it can’t find the calibrator. When you plugged the calibrator into your USB port, did Windows notify you it was loading a driver? If so, that could be your problem. You need to stop that automatic installation and do it manually.

You might try this: uninstall the Optix software and the go to the Windows Device Manager and install the driver from there. After you uninstall the driver, start with Step 5 in my instructions above to install the driver. Let me know if it works.

Good luck,


10 Doug August 13, 2010 at 7:48 pm

I uninstalled the optix 1.0. In the device manager the item with the yellow exclamation mark is noted as an unknown device unlike step 6 which indicates it would say X-Rite DTP94.

Maybe this is the problem. My device only says MonacoOPTIX on it. Nowhere on the box does it state the model number, other than a P/N MON-OPT. Do I have a lower grade unit that isn’t supported?

A scan of the box is at http://myredeemer.org/images/Monaco%20Optix.jpg

Each time I try to use the device mgr to add the driver, it says that no valid driver is found. That seems to prohibit going past step 6.

Thank you.

11 Doug August 13, 2010 at 7:53 pm

P.S. You might have to go to http://myredeemer.org/images/ first and then select the image:


12 Alan Haynes / PhotoCitizen August 14, 2010 at 9:55 am

Hi Doug,

I looked at the scan you uploaded: that IS an older model. The Monaco Optix XR is sort of egg-shaped while yours is round. Mine says “Monaco Optix XR” on the top and, on the bottom label, has the model number DTP94.

Looks like you’ll need a new calibrator. Here’s a list of new units that won’t bust your budget: Color Calibration Devices.

I’ve researched this a bit and, if I had to buy a new calibrator, I’d get the X-Rite i1Display 2. But a friend of mine is happy with the LT version she has, so I guess it works too – and it’s $50 cheaper.

If you have an older CRT monitor like I do, make sure you get one that can calibrate CRT displays. These days, not all of them do.

Good Luck,


13 Rose M. August 22, 2010 at 3:57 pm

Thank you soooooooooo much for this info. X-Rite has been very good in trying to help but the fact that you have done it is great. After calling them and finding out that the Optix XR PRO was the best calibrator they made I didn’t want to have to downgrade to a inferior calibrator so I am still running XP. I do plan to upgrade to a 64 bit system, hopefully I can find Windows XP Professional 64 bit as I need to purchase PS CS5 that will only run on 64 bit. I tried to use the Monoco system with Vista on my laptop but gave up. I’ve been looking for a solution. Although I do my color correcting on a desktop LED monitor and know laptops are not the way to go it would have been nice to do so anyway when I am traveling to get somewhat close. I can’t wait to try this. Thanks again so much for taking the time to post this. Rose

14 Peter Drewcock August 25, 2010 at 12:49 pm

Thanks for the great info. Unfortunately, EZcolor doesn’t seem to recocgnize my printer. Can anyone help? I can browse (find) the R1800 printer, but it will not connect to it. Cheers! Pete.

15 Alan Haynes / PhotoCitizen August 25, 2010 at 1:26 pm

Hello Peter,

I have heard from others that EZ-color no longer works with their printers. I gave up on calibrating my printer with EZcolor long ago (in the Windows XP days).

The profiles it generates are dependent upon the flatbed scanner you use to scan the color patches. This is not an accurate way to create a color profile. You’d be better off just downloading color profiles from the paper manufacturer if they have one for your printer.

Otherwise, get a custom profile made. Mine were created by John Watts at WattsColorLab.com. You can do it all by mail and it costs only $40 per profile. Best $40 I ever spent.

If anyone does get EZ-Color to work with their printer, I’d love to hear about it.

Good luck,

For those of you getting blue screens when trying to install the DTP94 driver in Win7 64-bit, it turns out to be caused by some sort of power problem. As the remark at the end of this x-rite page says, attach a powered USB hub to your computer, then plug the DTP94 into the hub. That let me get the driver installed without blue screening.


17 Alan Haynes / PhotoCitizen October 16, 2010 at 6:15 pm


Thanks for the tip. Some portable hard drives have a similar problem: they need more power than a single USB port can provide. So the hard drive manufacturer includes a dual USB cable where you can plug the hard drive into two USB ports simultaneously.

A powered USB hub doesn’t draw power from the computer’s USB ports, so it’s liable to solve the problem. For even more convenience, there are several powered hubs that also include a card reader for your CF, SD and other media cards. Here’s a link to a sampling of them.


18 Mike December 9, 2010 at 9:11 pm

Bob’s instructions for unblocking and deselecting the encryption did the trick for me. My system was a brand new installation of Win 7 Pro 64 bit. I’m using Monaco Optix XR Pro and the DTP94. So glad I found this!

19 Matt December 30, 2010 at 6:39 am

Thanks to John K for the USB tip. The repeated BSOD was driving me crazy… I’d managed to figure all the rest out but not that. Now I just have to get through the photo backlog that accumulated since I migrated to Win 7 Pro and couldn’t calibrate 🙂

20 Philip Tobias January 4, 2011 at 9:56 am

Thanks so much. Your clear directions got this driver and hardware working on Windows 7.

21 Alan Haynes / PhotoCitizen January 5, 2011 at 10:41 am

Hi Philip,

Glad to help.


22 Travis * Johansen January 5, 2011 at 1:17 pm

THANKS A TON! I was stuck having no clue what to do since I couldn’t find drivers online 🙂

Great article, flow, and nice looking blog. I will definitely check out your other stuff.

23 Dave Stroem January 5, 2011 at 2:44 pm

Thanks for the tips. I was just about to give up and plunk down the $$$ for a new spyder. Your step by step instructions worked perfectly and I am now looking at my newly profiled monitor.


24 Alan Haynes / PhotoCitizen January 5, 2011 at 8:04 pm

Travis and Dave,

It’s cool that our clunky old equipment from the Windows XP days (or earlier) still works with Windows 7. Think we’ll have to go through all this again when Windows 8 comes out?


25 Steve January 12, 2011 at 4:20 pm

I have a question, everything went smooth until I got to the enter the key page, the key page that came up to enter the old key into was different than the original key page, it had 4 blocks inside instead of one, so it kept saying that the key number was not correct, in other words there are not enough characters in the old key to fill the spaces in the boxes that came up, any suggestions would be greatly appreciated.

26 Alan Haynes / PhotoCitizen January 12, 2011 at 4:31 pm

Hi Steve,

I think you’re referring to the Customer Installation window where you register your EZColor software. It includes spaces for your User Name, Company Name and Serial Number. The Serial Number field is made up of four separate blocks.

My serial number begins with “EZ-EPSN25-.” So, I would omit all of the hyphens and type EZ in the first block, EPSN25 in the second, and so on. You don’t need to fill each block completely. Just use your tab key to skip from one block to the next.

It’s been a while since I installed this software, so let me know if it works by adding another comment here.

Good luck,

Hey Alan well I got to the setup wizard, I entered the serial number that was issued to me in 06, I got a message that says the serial number I entered is not valid.
In 07 I switched Vista and was given another serial number, I also tried that and got the same message.
Any idea’s



28 Alan Haynes / PhotoCitizen January 13, 2011 at 9:58 am


Is your serial number from version 2.5 of the EZcolor software? If it’s an earlier version, I don’t think you’ll ever get it to work. Also, did you download version 2.65 of the software from the link in my article above?

If the installation still doesn’t work, try this: download the trial version of Color Eyes Display Pro. It’s supposed to work with the XR calibrator. If it does work, you can buy the full version for $175.

Not cheap, I know, but the other alternative is to buy a new calibrator. It looks like the X-rite i1 Display 2 still gives you the most for you money (about $200). Here’ a link. Some people have said the software on the included disc does not work with Windows 7, so make sure you download the latest software for it from the X-rite website.

I’m please to announce that I got this to work, finally :>)

After going through Alan’s tutorial several times only to get to the point where I plug in my name business and serialnunber to hit OK and get a message that baisically says the serila nunber your using is not valid.

I unistalled all of the Monaco OptIx software, I called XRITE and asked the for a new serial number, I explained what I was trying to accomplish and they were gracious enough to oblige me.

So I reinstalled the original software, launched Monaco Optix XR and walla it worked it didn’t even ask me for the serial number and key.

I ran a profile saved it to my computer, My screen is calibrated, yeaaah!!!

Thanks Alan for your time and patience, I hope this helps others

Glad to hear that X-rite helped you out and everything works now. Perseverance and experimentation – the keys to computer maintenance.


31 Dan January 21, 2011 at 1:39 pm

Bless you. Bless your children. Bless your wife and your friends. Bless your house. Bless your dogs and cats. Bless your backyard grill, your lawnmower, and your plumbing!

Jokes aside, thanks for not only writing this tutorial but for doing it in a clearly-written, concise, and detailed way. So many people nowadays create slop that at best is hard to follow.

I didn’t need the entire tutorial, just the location of the driver. But I read thru it any way and found that you covered every screen, every prompt.

Well done!

32 Alan Haynes / PhotoCitizen January 22, 2011 at 7:21 am

Hi Dan,

My plumbing thanks you. You’re right, there is a lot of dreck on the web. I try to write clear and complete articles. Glad you found this one to be just that.

I’ve tried all the above several times to no avail. Just bought an externally powered USP port and when I try to calibrate it just says it can’t find the device even though it’s listed w/no exclamation mark. When I go in to update the driver to the new version it says, ‘windows has determined the driver is already updated’. I am running brand new Dell xps8300 with Win 7 Pro. It won’t load the drivers in compatibility mode either. The WinXP compatability mode says it can’t modify the necessary monitor files or somesuch thing I’m too tired t remember now. I’m frustrated…

34 JBD January 31, 2011 at 2:28 pm

Ok… today I decided to delete everything and start from scratch and guess what? It worked! Here’s what I did. Note that I’m not using the EZ Color software.

Unplugged DTP94 from my newly purchased externally powered USB hub port. Deleted the entire downloaded files and zip files that I had downloaded from Monaco’s download page (V. I made sure control panel didn’t list the DTP94 and that the software that came with the DTP94 was uninstalled. With DTP94 still unplugged from the PC, I downloaded the V. Zip file. Before extracting I right clicked on properties of the zip file and unchecked the encrypt box. I am on Win7Pro and made sure I have full control as administrator. When this step is correcltly done (the uncheck encrypt part anyway) the color of the extracted files are black instead of the previous green. I then (with no DTP94 attached still) installed the software that came with the OptixXR colorimeter making sure there were no error msgs. After finishing the install of the colorimeter software I plugged-in my colorimeter DTP94 to the externally powered USB hub port on my PC and I got a msg in the lower right saying Windows detected a new USB and successfully installed the drivers or something to that effect (it went away).

I then launched the calibration software (what came with the DTP94 Colorimeter), entered my software serial number (not the activation code since it was long ago activated), and next thing I know I’m ready to calibrate. I am using a new Dell U2311H LCD monitor on a new Dell XPS8300. The first measurements didn’t work well as I’m not extremely adept with the monitor controls on the first attempt and got a whacky profile. I made another attempt and it worked nicely using 6500 degree target point and 2.2 gamma. I am now calibrated! I think the externally powered USB Hub was the key along with completely unlocking the encryption.

Thank you very kindly for this extremely valuable site and clear instructions.

35 Alan Haynes / PhotoCitizen February 2, 2011 at 11:34 am


Isn’t it interesting how we all have to jump through different hoops to get the Optix-XR running. Thanks for the input. I’m sure it will help others.


36 Wayne February 9, 2011 at 1:43 pm

I ran across your helpful posting on Monaco EZ color. My question is even further out.

I have a couple copies of Monaco EZColor 2.0 along with a couple Sequel Imaging colorimeters I have a Windows 7 PC and wondered if it is totally impossible to get this to work. It still works fine on my XP Pro installations.

I contacted X-Rite and they said they didn’t even have an upgrade path or any sort of discount on an upgrade for either EZColor or the Color Works. That didn’t thrill me in terms of Customer Satisfaction 🙂

Thanks for your thoughts. Best regards,


37 Alan Haynes / PhotoCitizen February 9, 2011 at 1:47 pm

Hello Wayne,

I’m not familiar with the Sequel colorimeter. I imagine they use a different driver than the Optix XR. Have you tried to install it on your Windows 7 machine? The steps might be similar to what I had to go through with the XR.

If it doesn’t work, all you’ve lost is some time – and maybe a little hair from all the frustration.

Good Luck,


38 Wayne February 9, 2011 at 2:32 pm

Sequel Imaging was the brand of colorimeter that was relabeled as the “MonacoSENSOR” that was included with versions of MonacoEZColor 2.0 circa 2002. My main issue would likely be an updated driver and my research now shows that Sequel was acquired by GretagMacbeth and it appears that they in turn were acquired by X-Rite.

If I have anything resembling success, I’ll post info here!

Best regards,


In a week or

Hi Alan

This is a great service you performed. I have now installed the XR on a new 64 bit Windows 7 Pro Machine.

I received the “Access denied” message mentioned in Bob’s contribution (Aug 12th), but all was well after selecting ‘Unblock’ on the general tab, and de-selecting the ‘Encrypt contents to secure data’ option under the Advanced option of the general tab.

Hello Alan,

I’m happy that all my hard work installing the Optix-XR has helped so many people.

41 Steve February 28, 2011 at 6:22 am

I have everything working now except the new profile will not go into the startup menu, any suggestions would be greatly appreciated or how to extract the new profile and use it after I turn off the computer.
the way it stands now is I have to profile the monitor every time I turn off the computer.

42 Alan Haynes / PhotoCitizen February 28, 2011 at 8:16 am

Hi Steve,

If I understand you correctly, you have been able to create the monitor profile, but your computer does not automatically install it when it boots up.

Do you have an entry for MonacoGamma in your computer’s startup menu? On my Windows 7 64-bit machine, I click on the Start button, then right-click on >All Programs. Then choose Open All Users.

Now, a new window opens that contains the Programs folder. Inside that folder, you’ll find the Startup folder. It should contain a shortcut to MonacoGamma.

If it doesn’t, you can create a shortcut there and then enter these parameters in the shortcuts Properties window under the tab named Shortcut:

For Target, enter “C:\Program Files (x86)\X-Rite\Tools\MonacoGamma\MonacoGamma.exe” -StartUp -All (include the quotes).

For Start In, enter: “C:\Program Files (x86)\X-Rite\Tools\MonacoGamma\” (include the quotes).

If you’re running a 32-bit version of Windows 7, leave off the (x86) portion, so it will start out “C:\Program Files\X-Rite …. etc.

If you’re running Vista, this should still work – I think the path to the MonacoGamma software should be the same. If not, locate your MonacoGamma.exe file (somewhere in C:\Programs) and enter that information instead.

Let me know if that helps or if you need any more information.


43 Steve Agrella March 3, 2011 at 6:42 pm

Alan you are the Man, this workaround saved me allot of money, you solved my last piece of the puzzle.

My Monaco xr works perfect now, thanks so much for the time and effort you have put into thiis to help out your fellow Photog’s.

Thank you, thank you, thank you.

When I plug in my Optix XR it causes a blue screen crash. I am run a Toshiba computer with Windows 7 64-bit Home Edition. Any ideas as to what the conflict might be?


45 Alan Haynes / PhotoCitizen March 11, 2011 at 8:51 am


As usual, glad to help.


46 Alan Haynes / PhotoCitizen March 11, 2011 at 8:58 am

Hello Doug,

I assume you’ve installed all of the drivers and such. First thing: try plugging the XR into a different USB port. Second: try turning off the computer, plug in the XR and turn the computer on when the XR is already connected. Third: try reinstalling all of the Optix drivers and such.

Beyond that, diagnosing a Blue Screen of Death (BSOD) is a difficult – and very geeky- endeavor. Do a search in Google for how to diagnose windows 7 bsod.

Good Luck,


47 John March 20, 2011 at 2:00 pm

Your installation script worked perfectly on a new HP Win7 Home Premium box.

Thanks for sharing your knowledge.

48 Philip March 27, 2011 at 6:31 pm

Hi Allan…

I installed the software and after downloading your ZIP file for the drivers, I’ve installed the hardware… but when I try to run the run the Monaco EZ Color software (I’m running Window’s 7 Home edition), I get the following message:

“Can’t Locate Resource DLL for Application”

Have you come across this or have any ideas?

Thanks in advance…

49 Alan Haynes / PhotoCitizen March 31, 2011 at 1:31 pm

Hello Philip,

That’s a tough one to diagnose. You’re the first one to mention this particular problem.

The missing DLL might be part of the Monaco installation. Your best bet would be to uninstall the Monaco software (not the hardware drivers) and reinstall it. Follow the installation steps very carefully – maybe you missed something.

If that doesn’t work – and if the error message explains which DLL is missing – search for that DLL file on Google and see if you can find how to install it.

Sorry I can’t be of more help, but let me know how things go.


50 Irvin April 9, 2011 at 9:15 am

I recently upgraded my Windows Vista Home 64 Bit to Windows 7 Home 64 Bit. The conversion went surprisingly well and kept my previously installed programs available.

I followed you well written instruction for installing my EZ Color Suite and the Drivers for my Optix scanner. Everything work well.

Thank you very much for taking the time to pass on your experience and detailed instructions.

51 Emil June 2, 2011 at 7:05 am

Wonderfully precise and thorough instructions. Everything worked as predicted. Thank you very much for taking your time and writing it!

52 Alan Haynes / PhotoCitizen June 6, 2011 at 9:39 am


Glad to everything worked. Isn’t it nice to be able to keep using old hardware?


53 Greer Taylor July 18, 2011 at 6:58 pm

Yes it is great to be able to use old hardware – anything I do not have to throw out is good and good for the planet 🙂


54 Fred Martin October 19, 2011 at 7:43 am

Vraiment bravo!
Vos explications sont parfaites et votre site semble providentiel!!!
Des heures a essayé d’installer un équipement qui coûte cher en se disant qu’il faudra encore en changer pour cause d’incompatibilité, c’est déséspérant…
Votre démarche est vraiment civique dans un monde informatique un peu fou!
Merci encore.

55 Alan Haynes / PhotoCitizen October 19, 2011 at 12:38 pm

Bonjour Fred,

Merci pour les paroles aimables. Glad je pouvais l’aider.

56 HIDAMARI October 27, 2011 at 5:55 pm

Thanks for this writeup. It saved me lots of time. Really appreciate it.

57 Rob December 17, 2011 at 1:06 pm

Like many others, I too was experiencing the blue screen of death when I was attempting to re-install the driver on my Windows 7 OS. Just a word of advice for those of you still in the process of trying to get it going; you must plug the Optix device into a powered usb hub. Do NOT plug device into one of your usb ports on the computer. Failure to do so will more than likely crash your system and give you another blue screen to stare at.

The instructions provided worked for me and the calibration tool is back up and running. Thank you so much Alan; I truly appreciate the time and effort that you spent in providing such detailed and precise instructions. The last thing that I wanted to do was dish out a few hundred dollars to buy new equipment and you saved me from having to do that.

Best Regards,


58 Alan Haynes / PhotoCitizen December 26, 2011 at 12:26 pm

Hello Rob,

Some computers do not supply much power to their USB ports. This is more common on laptops than on desktops.

If a device requires more power than the USB port can provide, it will not function. In that case, a powered USB hub (one with it’s own AC adapter) will solve the problem as you mentioned.

Thanks for the tip,


59 larsenks January 24, 2012 at 12:41 pm

Before reading this wonderful helper which got me back to using EZ Color again, I too had problems with getting resource dll error messages. I think they were caused by trying to install the program software first, before the driver (in Win 7). The problem went away when I got the optical device and its driver working first, and THEN did a clean install of the main program per the instructions above. Hope this helps someone!

60 JW March 29, 2012 at 10:40 am

Tnx a zillion times. It works!
