First of all, it is highly advised that that you should uninstall the Cisco VPN Client by using the InstallShield uninstall utility packaged with the client (which can be located here: Start > Programs > Cisco Systems VPN Client > Uninstall VPN Client).

If these uninstall applications fail, you can uninstall the application manually by deleting files and modifying the Microsoft Windows registry.
