Hello Peru Bob I had the Nvidia Quadro Version 397.93 installed... I have a Quadro M200M graphic card... I down greadet to 397.93, 392.00, 391.89 and 391.74 and none of those worked... I downloaded these of course from Nvidia home page... Still the same problem with all of those versions... And theres still the program asking me if" i want to allow to this app to make changes to my device... Thank you so far;-) Cheers Raphael
