Could not access Modelsim in Simulation Library Compiler

There's a note there about the license file environment variable. Is that set up correctly? And what's your license setup for Quartus?

Hello

Welcome to INTEL forum. Could you help re-confirm your license setup again? You need to set your LM_LICENSE_FILE environment variable to point to the license that Intel provide. c:\intel\license.dat or something similar.

2nd could you also ensure the port number. The port number is required for Windows systems and it should be outside of the 27000-28000 range and be unique on the machine. For example, 1800.

Please stop and restart the server after assigning port number. You need to allow the firewall access to the port number from both server and client machine. refer this to your license server admin

You can refer to link on how to set environment variable.
