I recently installed a fresh copy of Windows Vista on one of my desktop. Installation went and it was working fine so far. Since past two days whenever I boot up my system I use to get a message saying the following:
"There is a problem with your license so notifications will no longer appear. You will no longer recive notifications, including those about your license or activation. Try to fix this problem, click one of the links below.
Error: 0xC004D401
Description: The security processor reported a system file mismatch error.”
When I try to validate by going to Microsoft website, it always give me an error message saying: “Unrecognized error. Error on Windows validation”. As I am not even able to validate, I tried changing my Vista Product key but every time it ends up saying
“Invalid product key
Code: 0xC004F033
Description: The Software Licensing Service reported that the product key is not allowed to be installed. Please see the event log for details.”
Now I have no idea left. Can anyone here please tell me what is wrong with my system and how can I get rid of this? Thank you.
