Two things you can try to do

  1. Go into Control Panel and select troubleshooting
  2. Under “System and Security , click “Fix Problems with Windows Update”
  3. Click advanced and select “Run as Administrator” (enter your administrator credentials if required)
  4. Click Next

The troubleshoot will return with a failed repair “Potential Windows Update Database error”

Great…

Doing that process it appears to temporarily kill off KB3189866 and allow other updates to install.

Great!

So you reboot… and find that the update still won’t download and run…

Solution

  1. Go to http://catalog.update.microsoft.com/v7/site/Search.aspx?q=KB3189866 and manually download it
  2. Then install it
  3. Reboot your PC
  4. Rerun the troubleshooting mentioned above and magically it will find no errors!
  5. Look in the Windows update history and you will set it installed.
