Any advice?
I say stay away. and buy an xbox copy or something

Only way i have been able to run this game (i have the steam version) is to use a cracked exe. Running it with the supplied one seems to either just crash the game or make it behave weird on modern systems.

I had a problem with the Gog version of KotOR 2 The Sith Lords and my old laptop, which has Intel integrated video, but it still worked with my origial disc.

Other than that, I can confirm both games work on both Windows 7 32bit, and Windows 10 64bit.

So it must be a configuration problem with your set-up, if it doesn't work.

I've never had a problem running it from Windows XP - Windows 10, with multiple hardware configurations (original discs, Steam and Gog). Android version works fine for me as well.

Are you using a dedicated GPU, or is it inegrated with processor?

Game works fine for me.
