When I try to install the firewall client, I get an error: 'Cannot find file c:\progra~1\microsoft firewall client\internal_setup\setup_a.exe (or one of its components). Check to ensure the path and filename are correct and that all required libraries are available' Has anyone seen this before? Cheers, John Burridge Disclaimer.
