By mistake I purchased the Windows 8 Pro Pack from my local Best Buy store. I asked the sales droid for Windows 8 Pro and was given the Pro Pack and didn't find out it was the wrong thing until I had it home and opened. Since I had the Pro Pack I thought I might as well download Windows 8 Pro and pay for it online rather than go back to the store.
My first attempt at installing it failed and the installer returned my system to its original state. I then burned a DVD of the ISO and made a dual boot system - Windows 8 64bit and Windows 7 64bit. Both systems seem to be running fine.
I have tried several times to enter the Product Key for the Windows 8 Pro Media Center Add On but each time I try it tells me that I can't use this key and will have to purchase a new one. I didn't actually want to purchase it in the first place but now that I have it, and can't return it, I would like to use it.
Any idea why it's not working?
Is there a way to get it to work?
If there isn't, will it work on someone else's system (can I sell it)?
