I seem to have the same problem every time in try to read a MS software key. What I still don't know is if Anytime Update would have worked if I typed the key in correctly. Reinstall went fine and only took a couple hours for OS, drivers, updates, Firefox, anti-virus and BF4. It was then that I realized after much trial and error that what I thought was a 'B' in the key was an '8'! Went through the process of a complete reinstall and when I got to the point of entering key, also got error that it was not valid. Tried to use Anytime Update from Win7 Home Premium, but was told key was not valid - which I assumed meant I had to do a complete reinstall (more on that later).
