Sorry to hear that reinstalling didn’t fix things.
SU 2017 runs fine in Win 10, PROVIDED that the stricter hardware, graphics driver and installed .NET and other Microsoft prerequisites are met.
I wonder if a Windows update might have affected the graphics driver?
I’m getting out of my depth here, and don’t currently have a Windows machine that will run SU 2017 (I use it now on an iMac).
Have you tried all the troubleshooting tips on the SU Help site? It gives a link to this forum post. There’s a whole list of things that have to be just right for it to install.
