Can I go from 32bit vista home to 64bit 7 ultimate.

I'm planning to do a format and clean install just not sure if this will work.

If you have 64 bit supporting CPU. You can Go.

But you have to do a clean install
(Boot from Windows 7 DVD,Format C: drive, New install of Windows 7)

In general, only old 16 bit programs will not run on a 64 bit OS.

Do you really need ultimate? There are very few facilities that a home user would want, compared to home premium.
