Activation issue is quiet common in many Windows stuff. I am not able to active Microsoft Office even after I have a license key with the same. I had contacted Microsoft a number of time. But they are not responding on the same. I had contacted the vendor about the issue, but they said the license is proper. After a few weeks when I tried back to run the update it is fixed. There is no issue. I can activate Office. So here it looks sometime Microsoft Servers are too busy for the same. Due to which you get the issue. Once those are back on work you can activate your product.

I had faced invalid key issue a number of time. I got the Media Center Edition from my friend. He was using this on his pc and later he sold that to me as he bought a new version. I contacted Microsoft for the issue. They said I will need to get a new one. Most of this OS and software's are single user license. That means you can use them only on one system. So if you are trying to install it on any other pc it might give you issue with activation.
