I tried dispwin on a WindowsXP machine and got the same behavior as under my Vista PC machine. I typed: > dispwin -V myCalibration.cal And it was successfully downloaded to my video LUT. Typing: > dispwin -V myProfile.icm Results in the same as above :( Maybe it's my Argyll version? The License file says "Version 3, 29 June 2007".
