My product id: 55041-148-1234855-86955
I cannot write for some reason.
I am trying to reinstall a product key that is not accepted. The product id is not recognized.
The product key <redacted>
is a legitimate product that I have got from Chalmers University and their connection to free operating system. It has worked before with this product key to activate win 7 Professional.
What is the reason that it does not work now when it has worked before? It is the same laptop as I have used before. Can you just use this product one time?
Please respond at once.
