Dear Forum Members, Can anyone please explain to me how to activate and register Windows 7? I have repeatedly been receiving the following error message; "A problem occurred when Windows tried to activate. Error Code 0x8004FC13" I have been trying to use the Product Key as provided before the commencement of the download and also I have tried other Product Keys as advised by Microsoft. Specifically I have attempted to re-download Win 7 RC1 multiple times and tried the "new" product keys provided (I didn't actually proceed with the download as I have an .ISO DVD copy of the program) however I persistently receive the same error message/code. Can anyone please advise me of what they think the issue and the solution might be? Thanks very much.
