Rhino 6 Won't Open After Installation!

Hi, I have had problems with opening my Rhino 6 Evaluation after installation.
I have tried everything suggested in the following thread:
Rhino 6 won't start after installation, but nothing has worked.

Reinstalling driver/windows updates, reinstalling Rhino Evaluation, repairing rhino, and running in safe mode/ as admin has all failed to work.

Help would be very appreciated

Please don’t double-post.
