I purchased a Win 7 home premium a couple weeks back. It came with discs for 32 and 64 bit versions. I installed the 32bit version as I was already running 32 bit Vista and just wanted to do an upgrade, not complete re-install.
Anyway due to various circumstances, I am now planning on a HDD format and clean re-instal and in such case would far rather go the 64bit route.
Question: after having activated my Win 7 32 bit, can I now install the 64 bit using the same license and activate it without problems, or do I have to fork out for another license, even thought the 32 bit version no longer is installed. My copy is a full version not an OEM discounted version.
