Installation Failed

Joseph, Do you any other AV product installed or previously installed on your system?.

Can't install Avg Antivirus free protection. Keep getting the message "Installation Failed, Error code: 0xC0070643, Description: Event exec_finished". I have tried  Avg remover tool with no help.

I installed the AVG removers and it only had AVG Zen to be romoved as an option.  I follwed the microsoft support link and in the anutomatic version detection results it said I am running a 64-bit system,  That's the file I chose.  
The same error code came up: 0xC0070643 Description: Event exec_finished
I don't have any other anti-virus programs.  Windows Defender has been disabled

Can I get one of those emails as well? I'm running Windows 8.1, and I've tried the fix it tool, removing it using the avg removal tool, and to no avail.
