AVG Zen free antivirus

Hello John,
We apologize for the inconvenience caused. Please remove conflicting antivirus products if any(http://avgclick.me/ConflictingApps). I suggest you to remove AVG traces using remover tool( http://aa-download.avg.com/filedir/util/AVG_Remover.exe ). Please restart to complete the uninstalling process. After running AVG Remover, you may need to manually uninstall/delete any remaining AVG applications from 'Control panel' and also 'search' for a folder "AVG Remover"(usually in 'C' drive) and please delete it manually. And then I request you to install AVG Antivirus Free(http://files-download.avg.com/inst/mp/AVG_Antivirus_Free_692.exe). Please follow these instructions and let us know the status. Thank you.

I am trying to install AVG Free anti virus on PC. It asks to restart the PC but then goes ahead and reinstalls. It never completes installation.
Any suggestions?
