Everytime I start up the game from Steam, it opens, and then I hit play.
About 2 seconds later a windows message pops up, 'FalloutNV is not working'.
I've uninstalled and reinstalled 4 times, and nothing seems to make it work.
Anyone have a solution?

story of my life brother, exact same issure here... pretty lame

I had the same problem until I disabled Spyware Doctor

I use SD! Well, used to before Win 7.

I would disable my Anti-Virus program, but I use Norton 360. I
'm not sure if theres a way to just disable it without having to pay to restart it.. It runs on a subscription.
