Vista Firewall Control?

I'm currently running Windows Firewall and Vista Firewall Control and need to remove Vista Firewall because it's prohibiting me from downloading new software/freeware. For example, I purchased System Mechanic Professional and it won't install because Vista Firewall is blocking it. I have searched everywhere on my computer so that I can remove it but I cannot locate the Vista Firewall application. Any suggestions? I would greatly appreciate the help.
