If you have a 64 bit cpu you can install a 64 bit OS, but you have to format, and do a clean Install. Windows won't do a upgrade install from 32 bit to 64 bit.
Forget about vista, get windows 7 64bit. However, the laptop only supports up to 4gb of memory. There really is no reason to upgrade to a 64bit OS if its max is only 4gb of ram.

He said he needs 64 bit to run that program, plus I have noticed a pretty decent difference in my CPU when it comes to 32 bit and 64 bit so I say always go with 64 bit.
