Upgrade to Win 8 32bit to 64bit

I've windows 7 Pro installed on my PC, i bought the upgrade through MS for about £25?? can't remember the correct cost.
anyway, my Win7 install is 32bit and the i downloaded the setup file from MS and got my key in an email, just wondering will the upgrade be just for 32bit or will it also work for 64bit
I'll clean install when i do end up doing it.

I do believe the way it works is if the PC you downloaded it on is running 32 bit Windows, your setup file(s) will be 32 bit. To get the 64 bit version you have to download from a PC running 64 bit Windows.

cheers for the reply.

sorry, i maybe worded my post wrong, it was more to do with the key, if their was any difference between a 32bit & 64bit key

I also pre-ordered Win8 so i have the 32 & 64bit DVD's

No problem the key is good for 32 bit or 64 bit, which one you use is totally up to you.

cheers, i'll maybe install it over the holidays
