From windows 7 32bit to windows 7 64bit

[Peeta]

I recently purchased the windows 7 upgrade to replace my current vista 32bit. I have already done the upgrade to windows 7 32bit. After researching, I'm thinking I should have gone with 64 bit instead. Is it possible to use my upgrade again to go from windows 7 32 to 64bit?

I know that I will have to do a clean install to go from 32 to 64... I just want to know if I can use my upgrade discs again.

yes you can use your upgrade discs as many times as you want.

I kind of have the same problem. I installed 32 bit and want to install 64 bit, and I won't have any issues with product keys?

not if you have a telephone. If it doesn't activate you can call up Microsoft and let them know you are switching over to 64-bit. You can activate by telephone.
