The Sims 2 Crashing on Windows 7?

This problem is probably your operating system. The Sims 2 and it's expansions weren't exactly desgined for Windows 7. Let along Windows 7 64-Bit. If you are really into the game, I would convert back to Windows XP or Check into having to operating systems on your computer. The Sims 2 is likely to have problems on Windows 7.
