You will have more problems using your HARDWARE, which will require
"Windows Certified 64bit drivers",  than trouble with your software.

MS has a tool for checking your software and hardware.
http://www.microsoft.com/Windows/windows-7/get/upgrade-advisor.aspx

You run this on the old computer (or computers) and it will
tell you about the "extra stuff" you want to "move" to Win7.
Ignore the upgrade stuff for the actual old computer itself in this case.

Side note: I tried (tested) Win7 on a Dell 2400 desktop and it ran fine.
I would have had to put a better video card in to get newer (supported) drivers,
(2400 video is an embedded chipset as you know),
but I did not want to "waste" a license + video card on a machine that old.

> What is the difference and what will having 64 bit mean exactly?
