I am using Window 7 with 64 bit. I started the game and it was normal. The game downloaded the patch automatically and I did not do anything. First game was fine. Second game crashed. Then, I read the forum and changed the exe file in the NF folder to Win XP compatible. After that, I tried a few more games. It has been fine after that (knocking on wood).
Hope you can find a solution.
Updates: I had a few more crashes, about the same frequency as before the patch.
Clarification: My computer already has those Microsoft Visual C++ files installed from other games.
