Hi B
You do not want to install your game in the program (x86) file as it is a directory with restrictions.
Set your SH4.exe as an administrator before starting the game.

Irrespective of what game version you have your stock game should be able to load to the games main menu.

Check that your gpu is correctly setup for any SH version.

It is also possible that a system update can change driver settings.
