This may be a Win10 bug and the documentation gives no indication that it will run on Win10. Only Graeme can answer this question.

Are you referring to the graphics card driver (Intel HD Graphics, in my case and already up-to-date) or the X-Rite driver standard default MS Windows HID Version 6.4.9879.0 (also up-to-date)? As already explained the ArgyllCMS.inf cannot be installed even after the "Disable Driver Signature Enforcement" startup. As I forgot to mention earlier, I am using the 64bit Win Version.

Anytime I start dispcal it crashes after "Setting up the instrument" (...) On Win 7 everything worked just fine, so the i1Display Pro should not be the problem. Does anybody of you have an idea what I should try next? Best Regards Tom Try to update the video driver. -- Best regards, Pictus mailto:pictus171@xxxxxxxxx
