I am trying to upgrade the free version which I have used for years with no problems upgrading. All of a sudden I get a message that says "Setup is unable to log into the True Vector service. Use the Service Manager to shut downs the True Vector service." Then, apparently it can continue the installation. What is the True Vector Service, What is the Service Manager and how do I get to it to shut it down? Thanks

Operating System:Windows XP Home Edition
Software Version:
Product Name:ZoneAlarm (Free)
