Forum:Vista crash to desktop

I installed the game fine and everything. It's just that when I click on the "Play" button on the launcher, it immediately comes up with a "FalloutNV has stopped working" CTD. I looked in my Event Viewer and came up with this:

Faulting application FalloutNV.exe, version 1.0.0.240, time stamp 0x4c9808f2, faulting module FalloutNV.exe, version 1.0.0.240, time stamp 0x4c9808f2, exception code 0xc0000005, fault offset 0x007c1a65, process id 0xf00, application start time 0x01cb7a0e6d7b7b4b.

I'm already running the game as an administrator (I'm running Vista SP1 on a laptop), and I just updated to DirectX9. The only possible reason that keeps crossing my mind is that I looked in my system properties and it says I only have 1GB of RAM.I've already uninstalled a ton of programs I don't need, and a defrag only cleared up 400some MB of disk space. The game itself is eating me alive at 6.5 or something GB.

Any help? I can provide more information if necessary.

EDITED by another user: I am having this exact same problem. If anyone knows a fix to this it would be great. Buying a game, spending a few hours to install it and finding that it doesnt work is every gamers biggest frustration.
