This error occurs because of the following reasons:

  • Windows 10 has not been activated properly in your PC
  • There is an update error
  • Device drivers may be causing problem during update
  • Corrupt Upgrade files have been downloaded

To verify correct activation, run the Troubleshooter and analyze the error. If it is a corrupted files error then delete them and download again. Search the solution according to the problem depicted in troubleshooter.

Another method is, open the Command Prompt and type ‘REAgentC /Disable.’ If it gives a message of successful operation, then restart your PC and again upgrade it.
