If that doesn’t work then it will most likely be an issue with the WMI repository on your PC (https://en.wikipedia.org/wiki/Windows_Management_Instrumentation) that is used by our authorization.
It may have been corrupted by a virus or a cleaner utility. It will need to be rebuilt, it has probably been affecting other programs too. Certainly, the authorization process for the plugin will be broken.
It's a fairly simple process:
1. Log onto Windows with an administrator account, click Start, type services.msc in the Start Search box, and press Enter.
2. In the right pane of the Service console, locate and right-click Windows Management Instrumentation, and then select Stop to stop the service.
3. Start Windows Explorer, and then locate the %SystemRoot%\System32\Wbem\Repository folder.
4. Backup and delete all the files in the %SystemRoot%\System32\Wbem\Repository folder.
5. Restart the computer.
The files that were deleted will be re-created when the computer restarts.
If this doesn't work, the WMI repository might be broken. The steps to fix can be found here.
