I keep receiving error code 0xc0070641 when I attempt to install AVG PC TUNE UP as part of the AVG ZEN package.
I had uninstalled AVG 2013, LINK SCANNER and TUNE UP UTILITIES 2009 prior to installing AVG UNLIMITED.
Despite uninstalling AVG ZEN using the AV removal tool and reinstalling the software the error persists
