If you are attempting to install our software behind a firewall (possibly a work computer), you will need to open TCP port number 16841 for outgoing connections only. If you are not familiar with configuring firewalls, please contact your Network Administrator with this information. If this is for your home computer, it may be that you’re using a router with a built in firewall, please refer to the router documentation for assistance. If you’re still having difficulties, please contact the Customer Support Team.
