sirana Posted July 12, 2016 Share Posted July 12, 2016 Did you modify the driver? In that case you would need to disable driver signature enforcement (at least under Windows 8, 8.1 and 10). Quote Link to comment Share on other sites More sharing options...
magicalillusion Posted July 12, 2016 Author Share Posted July 12, 2016 problem solved, installed win7 and the drivers installed smoothly Quote Link to comment Share on other sites More sharing options...
sirana Posted July 12, 2016 Share Posted July 12, 2016 Then it's pretty likely that you just had to disable driver signature enforcement in Windows 10 or 8. Because windows 7 doesn't have driver signature enforcement, so your drivers installed smoothly. In case you want to go back to the newer OS, http://www.howtogeek.com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/ Quote Link to comment Share on other sites More sharing options...
