How do you fix it when batman Arkham asylum has a general protection fault

"This thread concerns two problems I experienced with the GOTY Edition of Batman Arkham Asylum. I was not able to start the game. First, the menu of the preferences was unreadable due to a error message with some bla bla like ".Net Framework error"....and the game start has been canceled due to a "General Protection Error"...many persons have exactly those problems. I did a few steps that helped me, but I don't know which one exactly gave me the solution. Repeat it and post, if it helped you.

1st step: Open C:\Programm Files (x86)\nvidia corporation\physx\common .... copy the 4 *.dll-files and paste them into the batman GOTY\binaries folder...

2nd step: Open \batman GOTY\bmgame\config folder ... open the defaultengine file and search for

[SystemSettings]
DetailMode=2
ResX=1680
ResY=1050
Fullscreen=True
AllowD3D10=True

Change them as seen here...put your right resolution here, mine was 1680x1050, change fullscreen and d3d10 to true. then change menu resoultion:

[SystemSettingsEditor]
ResX=1680
ResY=1050

....I hope this helps you. Of course you need newest version of all your drivers and games for windows.....but orher threads already mentioned this. I use NET framework 4 with Windows 7 x64...."
I got this from another site a guy posted this .
