Need Help:QuestaSim Simulation report "Invalid license environment" with a valid license file.

Hi

Welcome to Intel forum. Could you help re-confirm your environment variable setup again? But before setting up Questa, would you kindly help check, whether your machine is supported or not (OS) by referring to link below:

You need to set your LM_LICENSE_FILE environment variable to point to the license that Intel provides. c:\intel\license.dat or something similar.

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

To make this entry, you may perform a windows Search for "System Variables" and then click on "Edit the System Environment Variables" and then click "Environment Variables". Be aware that you must add the entry in System variables, not user variables.
