I have a user that is getting "A license file is required to enable compilation of your design for the family of devices."


When they were here at our location, they were able to connect to get license. When they returned to their location, they can't. Adding server to the host file did not help.​ Any ideas?

Welcome to INTEL forum. This could probably a connection or VPN prob. My suggestion would be:

 1)     After VPN connection is established, setup license path in Quartus II>>tools>>license setup.

2)     Verify license server is running by using “lmutil lmstat –a –c <port>@<server> in BOTH server and client machine.

3)     Ping license server via VPN or telnet <host>< port> to check the TCP connection is established


Please stop and restart the server. You need to allow the firewall access to the port number from both server and client machine.


You can also refer to link below for more detailed instructions for Setting up a floating network license server (page 37 of 59):       


You can also refer this following YouTube for license setup.    


You can also refer to this following YouTube on Setting up and debugging Quartus floating licenses.    


Let me know if this information is helpful
