Nope, I don't know. I don't see why so many people have trouble running the game. When I first started playing MTA (back in 0.3) I just went out and bought GTA Vice City, installed it, then installed MTA and I could play fine with no problems. Same happened for the next 2 versions. Then MTASA Race came out, I already had GTA San Andreas installed so I just installed MTASA and it worked fine again.
