creating LM_LICENSE_FILE variable on Windows

The LM_LICENSE_FILE variable needs to be set properly. It should be set on the clients in order for our program to know where the license manager is running. It should include the port number and the server name. For our example: 27000@engineering1 .

System Properties menu

Right Click on the My Computer icon.
select the Properties option.
select the Advanced Tab.

Environment Variables

Now click on the button Environment Variables.
You need to define an environment variable (can be user or system) names:
LM_LICENSE_FILE
and the value is the port@server_name.
In our office the license server is a machine called blade1500 and it listens on port 1701.
Here is a snapshot of my environment variables.
