License Environment Variable Setting

Note: This setting only applies to on-premises licensing.

The environment variable ALTAIR_LICENSE_PATH is used to point to the license file or server.

ALTAIR_LICENSE_PATH must point to a valid local license file or to a network license server in the form of port@servername, for example, 6200@licsrver.

In the past, the environment variable was either LM_LICENSE_FILE or ALTAIR_LM_LICENSE_FILE.
