For those of you like me who have a DTP-94 and recently upgraded to Windows 7 64-bit I should warn you that you might run into a bit of a problem. Although Xrite's DTP-94 Driver Page
says that it works for Vista 64bit, when I tried to install this driver on my Dell Latitude D630 with Win7 64-bit, it gave me a bluescreen of death (BSOD)! A bit of searching shows that I am not the only one with this bluescreen problem, although some people are
able to get the DTP-94 to work on Win7 64-bit.
One thing I realized is that even if I got the DTP-94 to work with this new driver (called XrUsb64.sys) I still have the problem in that ColorHCFR specifically wants the older XdsIII.dll
driver when the meter is set to DTP-94. I do not believe it is (currently) possible to tell ColorHCFR to look for another driver file; please let me know if this is incorrect.
However, there is a solution! If you have Windows 7 Professional, Ultimate or Enterprise edition you can download Windows Virtual PC
for free and enable XP Mode
. You then install ColorHCFR and the older Monaco Software inside XP Mode. Once that's done, plugin the DTP-94, you'll notice that the Win7 desktop still complains it cant find the right driver for it, but all you need to do is go to "USB" at the top of the XP Mode virtual Window, click on "USB" then select the X-rite DTP-94 and tell it to "Attach". This will then prompt XP-Mode to look for the driver and this time it will automatically find and install the 32-bit Monaco driver. Finally, copy over XdsIII.dll from your Monaco folder over to the ColorHCFR folder and everything should work!
*Note, if you no longer have the older Monaco software or you bought the DTP-94 bare you can find the the XdsIII.dll bundled in with the Coloreyes Pro Demo Software
. It's located in the root install directory.
