Ok, so I just downloaded FS 2000 (It's probably the only one that'd run smoothly on my old PC)

I downloaded it from Ares (similar to LimeWire, BearShare, etc.)
When I opened it a zip file opened. I unzipped it to My Documents. When I click the install button, It won't work.

I'm really ****ed if this doesn't work because it took me 4 hours to download
lol...

Thanks for the help
