I sold an older computer running Windows 7 and now have a Windows 8 Home 64 bit machine. The game ran on 7, but just doesn't start on 8. I've been through many discussion boards trying different things such as:
a) Checking Compatibility setting on Steam files.
b) Steam Support advised using regedit to check permissions.
c) One discussion board claimed that unhooking controllers might do the trick.
d) Installed some file in Steam/Games directory: dinput8.dll
e) Insured I'm not running Steam beta client
f) Doesn't even run in Safe Mode
It just doesn't work. I need a real solution.
