Well, I played it on a Windows 7 (64 bit) system on my old laptop, but not for long since I installed XP on it (being that it was an older laptop and didn't run very smooth in general).

It completely depends on your system specs, if they are good enough to run Sims you can run it on a 64-bit system. But when you first play it I recommend you run it in compatibility mode just in case it crashes some time.

I don't think hardware is going to be a problem with Sims 1. The game itself has lower requirements than Windows 7, so if the guy can run Windows 7 with ease in the first place he will most likely have enough machine to run the game too.
I would not run in any compatibility mode unless I know it's 100% needed or have a strong reason to do so. Just my opinion. I like to run things in the most "natural" way as possible.
