And how can I upgrade to the 64 bit version?

Hi dlangan

To add to this you can not upgrade to Vista 64 bit it has to be a clean install only

there is no upgrade path from 32 bit to 64 bit !

And you need to make sure your hardware has the 64 bit drivers before you buy it

this includes your PC , printers ,  and other add on hardware same for software most of the 32 bit software will work but if it has to install a driver or some audio or video codes with it it may not work !!

Good Luck
