Windows 7: Dual boot 64/32 with the same licence

chucker · 26 Sep 2010

Can I install both Windows 7 64 and 32 bits on the same PC as a dual boot ? I have only one licence (2 DVDs Win 7 premium version : one 64bits and one 32 bits).
I'd like to have the 32bits version to keep on using programs that doesn't support 64bits version, even in compatibility mode, and the 64bits version in order to be able to use my 4 Go of RAM.

Thanks

Yes you can in separate partitions, as long as only one OS is running at a time, I believe

Hello Chucker,

Sorry, but no. You can only use the product key to activate one copy of Windows 7 at a time. If you want to activate another copy (ex: 64-bit vs 32-bit of your Windows 7 edition), then you will have to uninstall (format) all previous installations first.

You would have to have two product key numbers for what you are wanting to do.
