Hm. Ok. That is the OEM product key and it won't work. I believe that in a previous post you mentioned that you tried to enter the product key that you have. Where did you get it from? On the outside case of the computer? That should be the one to use. In the past, I have used a program called Belarc Advisor that performs an audit of the computer and will include all the product keys to all MS software installed that requires a product key. Here's the link to that download if you'd like to try.Belarc Advisor
Or you could try The Magical Jelly Bean Keyfinder
. Choose the free version.
If you only performed a repair install, one of those programs should find the product key.
Let us know if that helps. Besides having to call MS, Ztruker may have another idea.
