I ended up getting them installed by resetting windows 10 back to a default
Well not entirely default. What I always do with any PC is get a basic
setup running and then image it so I can always restore to something that I
know works without losing any files or programs.
I spent many hours trying to diagnose the issue on the driver installer
with no luck. Even older versions of the drivers had the same error. My
best guess is that it was a Windows insider build issue. I was using
insider builds for a long time and then I took myself off them and it
likely caused an issue somewhere that was effecting more than I could see.
Thanks for the reply. Hopefully someone else gets some benefit from it.
By the way these new drivers are excellent. Performance has improved quite
a bit. I was running fallout 4 at 60 but it was highly unstable. Now I'm
locked at 60fps 90% of the time. Just Cause 3 also runs at a nice stable
60 at 1080p with all settings maxed.
Great job team red!
