Change from 32bit to 64bit

  olyman 11:27 14 Dec 2013

I bought Windows 7 Home Premium when it first came out and received discs for both 32bit and 64bit ( not upgrades but the full versions ). I installed the 32bit version as I wasn't sure of 32 bit driver availability at that time. If I install the 64bit version on the original PC will Microsoft still accept the same Product Key? The PC has had replacement hard drives and extra memory installed. Also is it possible to run both versions with one on a Virtual Machine if there are external hardware or program compatibility problems? I assume that backed up data on external drives will run on either version.

Yes you can install the 64-bit version with the same key. You might have to activate it over the phone (free). I'm not sure but you might even be allowed to dual boot with the 32-bit on the same machine. Have not tried it with a V.M.

You can't run both versions on the same machine, that's the first answer. If you want to use the product key to install a different version on the same computer you must uninstall the first version.

The answer to your question about data backups is yes, the files will open in either version of Windows.
