Some Altair programs will require you to define environment variables prior to run.

In this article we will see how to define the environment variable ALTAIR_LICENSE_PATH=6200@licserver, where ALTAIR_LICENSE_PATH is the variable name and 6200@licserver is the variable value.

To define an environment variable on Windows please follow these steps:

1. From your Start Menu, click on the Settings cogwheel:
   
    
   
   
   
2. In the Search filed at the top, type environment then pick the Edit environment variables for your account entry.
   
   
   
   
   
3. Click on the New button:
   
   
   
   
   
4. Fill in the variable name (here ALTAIR_LICENSE_PATH) and variable value (here 6200@licserver), then click on OK.
   
   
   
   
   
5. Click on OK once more to close the Environment Variables window.
