Ive got the 32 - bit edition of vista, but was wondering if I could install 64 - bit using a different disc, but the same cd key. Just interested, anyone know?

If you have purchased the retail version MS will send you the 64 of the same version (business, ultimate, etc) for a nominal fee.

Nominal fee being about $10.00, shipping included, at least thats what it cost me within the US.
