It does run but crashes every hour or less. I posted in a game forum and a couple of people agreed that it has problem running in win 7. But I hope that somebody out there may have a fix for it. Instead of posting also my system specs, it suffices to say that ME 1 and 2, DA2, stalker, far cry, bioshock all work fine. I also have tried some suggested fixes such as dx9 etc. It is also not because of the 64 bit problem since I used to run it in windows XP 64 bit and it ran very well.
