This is a little complicated, so it bear with me for a minute.
I bought the Windows 7 Professional 64-bit Upgrade kit from software4students.com - Windows 7 Professional - Microsoft Windows 7 Professional 64-bit edition
This is a Microsoft approved distributer of Microsoft licenses, and my license key for Windows 7 as an upgrade is valid.
On installing Windows 7 onto my laptop, I thought "My Windows Vista installation is taking up 40gigabytes of space, I'll just format and install!". This led to me being unable to use my product key to activate my Windows 7 installation, since although it required a clean install, it didn't want my install to be clean of a previous Windows installation.
The course of action is obviously to reinstall Vista and then install Windows 7 on top of that. The only problem with that course is that my Vista key is not being accepted by the Vista installation at all
. The Vista Home Premium 32-bit operating system simply won't allow me to install it on my computer. Period. It says the OEM key which is on the bottom of my case is not a valid key.
So I have a Windows 7 Professional 64-bit Upgrade currently installed, but impossible to activate, and a Vista Home Premium key that is invalid. I'm in a big catch-22. Any suggestions?
