No Avast Firewall

I have used Avast Internet Security for quite some time. I recently had to removed Avast and when I did the reinstall it would not install Avast firewall, I even tried installing the firewall from the uninstall program, came up with an error saying it could not install the firewall. I even used the tool to remove all of Avast and then preformed another fresh install.

I am using a AMD Phenom II x 4 955 Processor 3.2GHz with 8 GB of ram on a Windows 7-64 bit.
I do used to consider myself an advanced user but this time I’m stumped! :-\

Any ideas?? Please email shoprat008@msn.com

what AV did you use before installing avast?..did your computer come with a factory installed trail AV ?
have you uninstalled this?
did you run the vendors removal tool to clear any leftover file that may conflict?

if not you find the tool here. http://singularlabs.com/uninstallers/security-software/
