Hi Robson,

This error message indicates some Windows system files have a date in the future. The Licensing system is designed to prevent users from circumventing the license expiration by changing the system clock. So, when any change in the system clock is detected, the license will become invalid. Restoring the system clock to the correct time will not automatically correct this problem. 

Please make sure your system is set to the correct time. If your system clock was changed recently and the clock setting is correct, then do the following:

Scan your PC for all files with future dates. Possibly, you may find a few folders/files dated in the future. Try to change the date to the current date and time. If the file is blocked, try to uninstall this with

Add/Remove program and reinstall afterwards.

Another option is to use Windows installation media to repair the Windows installation.
