I'm running Win7 64 bit with 6 gigs of ram yadda yadda. I was having the same crash problems that seemingly many other people are having. (I couldn't even get past the launcher) So I have Microsoft Security Essentials for anti virus. I added the FalloutNVLauncher executable to the process exceptions. Now I can actually get the launcher to...launch. It's been working so far, I hope this helps some of you that are running into similar issues. :rock:
