    I ordered the Vista Home Premium upgrade the first day it came out. I installed the x32 version of it. I recieved an email from microsoft saying that for a limited time I could order a x64 disc for the cost of shipping and handling.

     

    I wait a few months until today. I installed the disc (x64) but now I'm getting the message "The product key you typed is already in use".

     

    I bought a fresh hard drive and the old install of x32 is still on the old drive, should I delete it and would that solve my problem or is it a registration problem?
