Compatability?
 

Hi - just got a new Dell laptop w/Windows 7. Will SH3 work w/this OS??

Yes, but judging by what I've read here some users have to do some tweaking to make it work and some don't.

I'm on XP myself so don't have firsthand experience with it yet, but do a search of the forum for "Windows 7" and you'll find a lot of stuff posted about installing and running the game with that OS. There are at least a couple threads dedicated to the subject IIRC including one stickied at the top of the forum.

This might be a good place to start:
