Did you ever get Fallout 3 running? If not, this thread (http://steamcommunity.com/app/22370/discussions/0/828937546147175081/) has what you need. All you will probably need to do is 'update Games for Windows Live' in step 1 and then make the changes listed in step 4. If you are interested in the Unofficial patch listed in Step 6, there may be a way for me to get you the file without you having to register to download it. Once you are through Fallout 3, I may have a copy of Fallout New Vegas to send. ;)

Thanks for the link! My boyfriend literally spent hours a few weeks ago trying to get it to work with no luck, so I hope this works *crosses fingers*

I hope it works, too. It worked on mine and my parents' computer and most of the responses had great luck with it. Has the bf played it before? If not, it's a great one to play with someone else watching. Some of the situations and dialog are classics. I still fire it up periodically (the night I posted this, actually) and go around blowing up cars and looking for any loot stashes or landmarks I may have missed. Surprisingly, after three full play-throughs, I do still find things I hadn't seen before.
