Error updating AVG Free. It can't 'repair' and it won't uninstall either

Hi,

We regret for the inconvenience caused

We will help you to resolve the issue.

Can you send us the screenshot of the error message to examine the issue further?

Previous email:
I have been unable to update my antivirus.  It says ‘An error occurred when saving the current configuration. Connection is off-line.’ My Internet connection is fine and when I go through the following instructions that are provided and go to uninstall, then repair it says ‘There is a problem during initialisation, and then ‘invalid parameter specified’.  What do I need to do?


Many thanks for your email.  I have tried following your link, however it then says "installation already in progress.  ERROR CODE: 0xe001f921"
 
What should I do next?
 
Many thanks.
