Failure to install - 0xC0070643

Tony, Did you download & run the McAfee total removal tool (http://us.mcafee.com/apps/supporttools/mcpr/mcpr.asp)?.

I cannot install my coverage. I have uninstalled McAfee and still can't install AVG.

Hello Tony,
We would request you to run the AVG remover tool to remove all the remnants of the failed installation and re install AVG using offline installation file based on your OS ( 32 bit or 64 bit).
To run remover tool, please visit http://www.avg.com/tools#tba2 and click on "AVG Remover" to download the remover tool and run it on your PC. It will ask you to select which product you would like to uninstall. Please select "AVG Protection" and follow the setup instructions to uninstall AVG.
