The LM_LICENSE_FILE variable is important and needs to be set properly. It should be set on the client computers in order for our applications to know where the license manager is running. It should include the port number and the server name. For our example: 50000@ipppflex1 .


LM_LICENSE_FILE environment variable can be used any FLEXlm application and in many cases is not recommended. NUMINNO_LICENSE_FILE is specific to our vendor daemon, NUMINNO, and will not be recognized by other FLEXlm applications.  Our applications may still read the LM_LICENSE_FILE variable if it is set, before it reads NUMINNO_LICENSE_FILE. One of these variables must be set for clients of a redundant server triad to function properly.

Update the Environment Variables (Windows)

  1. Go to System Properties
  2. Select the Advanced Tab.
  3. Press button "Environment Variables"
  4. You need to define an environment variable (can be user or system) names: NUMINNO_LICENSE_FILE  and the value is the port@server_name.
  5. Restart Client (allows the new environment variable to be recognized).
