Hi tropicalvic,

Let’s follow these steps which should fix the issue.

Step 1

If you have any third party antivirus software and firewall disable them temporarily and make sure that the Windows Firewall is turned on. Then check if the issue reappears.

Step 2

  1. Open Run, and  type in services.msc then press Enter.
  2. In services window, locate Windows Defender service in the services list.
  3. Verify that the Status is Started. If the Status column is blank,

right click on the service and select Start.

4 If you get error trying to force start the Windows Defender service, try to change the Startup Type to Automatic, and then restart the computer.

Hope the information helps. Please post back and let us know.

Regards

    When I did the trouble shooter, I was instructed to unplug printer and any other items connected to my PC, then retry the update. The update was successful. After the update was completed, I re-connected my printer and so far, the error has not returned. Maybe that will work for you, good luck....
