Upgrade to Vista 64

[ccooper1025]

Atm I am running just basic windows xp home edition i guess its just the 32bit. My question is, is it possible to just buy the upgrade to vista 64 home premium disk or do I need to go and buy the Retail version of it.

You can not "upgrade" from 32 bit to 64 bit. You must do a clean install from scratch.

You do not need to buy the retail version, however. An OEM will be fine.

(1) There used to be a trick to do a clean install from an 'upgrade' disc - I do not know if it still works, but here is how to do it:
