BF4 Beta is here and sadly, it's only 64 bit while I'm still running 32 bit :(. But I read somewhere that a Windows 7 32 Bit key will work for the 64 bit version too. My friend is running 64 bit windows 7.
So here's my question.
If I uninstalled Windows 7 32 Bit, then put the Windows 7 64 bit CD in, then used my 32 Bit key, would it work?

I have already installed the WIndows 7 32 Bit.
The WIndows 7 64 Bit has already been installed too.
I reinstalled Windows 7 32 Bit recently.
I will be using the same motherboard
Just some info up there in case it will help.
 
Should not, go ahead and activate your 64 bit Windows with the key. If there are issues, which there should not, Microsoft tech support can easily solve any key issues for you.

The key is for 1 copy of Windows though, not 32 on one PC and 64 on another.
