New iMac, new installation of freshly downloaded Parallels Desktop 6, and brand new Windows 7 installation disk. Tried to follow all the instructions on the Parallels website and in various forums (I thought I had researched the heck out of this before starting), but the Windows 7 installation process running in Parallels Desktop refuses to accept the Product Key on the label in the Windows 7 package I unwrapped today: "The product key is invalid". Tried to call Microsoft thinking it was a validation problem, but they kept asking for an "installation ID" number which does not appear anywhere. I don't see a backout method to abort this attempt until tomorrow, so I guess I'm going to have to simply close the Parallels desktop window or Force Quit if need be, but that's in the middle of the Windows 7 installation. Bummer. Any suggestions? Microsoft Tech Support told me to call Customer Support, but the automated voice there says this is outside business hours. Dead in the water for now.
