Windows 7 "Invalid Product Key" Boot Camp 3.

Lucas Littlewood wrote:
I have installed Windows 7 Pro through Parallels and it activated fine, after deleting the virtual machine and then tried installing it through Boot Camp it installed fine but when it came to putting in the product key it would not accept it, it is official as I bought it through the Microsoft website and it activated through Parallels. I can't understand why it won't activate through Boot Camp? Please help!

Windows sees different hardware (network adapter mac address, etc.) now that you are installing with Bootcamp than when you installed with Parallels. This is why it is wanting another activation (it thinks you are installing on another computer). Did you try the activation process when it gave you the message? It is an automated process that is easy to complete. If the online process does not work, call the activation number and you'll be guided through an automated process. Again this is a simple to follow process. And the second activation is free.
