Also, I notice that you did not specify which game you were talking about.
Also, they forgot to specify what GPU they have, if it's some sort of Intel integrated chipset they're in for a world of trouble getting KotOR or KotOR II to run.
[EDIT] OP, if you have an ATI/AMD GPU, delete both ati .dll files in the game folder (atigktxx.dll and atioglxx.dll, respectively). It's an easily skippable fix but it worked for me. These should be found in whatever folder you installed the game, and I say this because I was having the exact same problem when I installed the game. It works for both KotOR games.
