C:\FlexNet_11.16_Dymola\LIC\

1.2 Open your license file with a text editor, replace "server.name.here" with the computer name of your hardware.
Add a free port to the SERVER line (e.g. 27004) and add another free port to the VENDOR line (e.g. 28004 - see picture below) and save the changes.

Don’t forget to open these 2 IP ports in your firewall so that client computers can connect to the FlexNet service.
