Getting an error code 0xc0070652

Hello Charles.
You may also receive error code 0xC0070652.
The issue is caused by a Windows installation process running in the background. The resolution is as follows:
Make sure that no other installation is running on your computer. If you discover another installation is in progress, please wait for it to finish and retry the update later.
Press simultaneously Ctrl+Alt+Delete keys on your keyboard.
On the next screen, click on Task Manager.
In Task Manager, on Processes tab, look for an item called "Windows installer" or "msiexec.exe".
Left-click the "Windows installer" to select it and then click End task button in bottom right corner of the Task Manager window.
A prompt will appear to confirm the action. Click End task again.
If there are more instances of "Windows installer" or "msiexec.exe" displayed in the Task Manager window, please repeat the steps 5 and 6 for all of them.
Return to AVG and run the update again.
Thank you.

I tried to fix it and to uninstall it to reinstall it but it will not allow me to.
