Hi
But before setting up license, would you kindly help check, whether your machine is supported or not (OS) by referring to link below:
https://www.altera.com/support/support-resources/download/os-support.html
The error is most commonly caused by the default ports are being used or a VPN/Firewall setting stopping the connection.
Make sure the port used by license server or vendor daemon is not blocked. The port number is required for Windows systems and should be outside of the 27000-28000 range and be unique on the machine. The following example shows how to specify port numbers in a floating license file. example, specify ports 1800, 1801, and 1802.
SERVER myServer 0123456789ab 1800
VENDOR alterad ./alterad port=1801
VENDOR mgcld ./mgcld port=1802
Please stop and restart the server. You need to allow the firewall access to the port number from both server and client machine.
If you have a Firewall or have other License servers running on the same machine you may need to change the Server Ports, this can be done by clicking the Server Ports button. FlexLM Port: Change this to avoid port conflicts If you have other License servers - the default is 27000
