I attempted uncessfully to install comodo personal firewall, but failed and recieved the following error message: “Error 0 running command .\CPF_Setup_22.214.171.1245_XP_Vista_x64.exe” I had previously used ZoneAlarm firewall, but had uninstalled it before attempting to install CPF. I had also run a registry check before attempting to install CPF. I use Avira free antivirus. My operating system is Windows XP home edition, and my processor is a 64bit AMD Athelon 64 XP.
My thanks to anyone who can help me with this mystereous problem.
