Windows 7 32 bit to 64 bit?

[omega2551]

I want to take my Windows 7 from 32-bit to-64 bit. I know that to get from a 32 bit OS to 64 bit you have to do a clean install. Problem is, i upgraded to 7 from Vista about a year ago using a 32 bit version downloadable installer so there's no discs with 32 and 64 bit version. So I guess my real question is can i use a 32 bit upgrade version's key on a 64 bit non-upgrade version? I could download a 64 bit version ISO and do a clean install with that, right?...as long as the key i already have would work?

Hello,
If you have a valid 7/32 key you can use that on 7/64 but you have to call activation - auto activation did not accept my 32bit key!

So it doesn't matter that my key is from an upgrade version?

One key works for both versions, 32 and 64.

Use phone activation, start>slui 4>follow the instructions.
