Where did you buy it? The retail is supposed to include both 32 and 64 bit versions.

The key works for both versions.

Vista/Windows 7

yeah i think it will work...I bought a retail version of home premium and got two discs in the box one 32bit and the other 64bit and one licence key so I guess I can use that key for both discs :)

Good to know if I do decide to go 64 bit in the next few years :)

The keys do not distinguish between 32 or 64 bit. You can use the key you received at the Microsoft conference with a 64-bit copy of Windows 7 Ultimate and it will work fine.

TechNet or MSDN - one of the folks you attended the conference with will probably have a subscription.

Eventually there will be a program similar to this one for Vista:
