AVG Free will not install

Hello Cathy,
We do not recommend our user to run two antivirus programs at the same time. Because a competing antivirus program that is monitoring and sending information about your system tends to look like a virus, so it will attempt to block and remove each other.
You can uninstall McAfee Security, if you're trying to install AVG Antivirus Free.
I also request you to check if Windows Installer Services setting is automatic, press Windows Logo+R: Run dialog box and type Services.msc , look for Windows Installer.
Regards,
Alok.

Hi. I am able to download the Install file, but when I either double click the file or open the containing folder and select run as administrator, nothing happens.  I turned off my McAfee firewall, anti-spam and real-time scanning and still nothing happens.
Please help.
