Disable Network License Manager for MATLAB Parallel Server

To change your installed network license manager to online licensing, you must shut down the service and either delete the license (if the license manager was only for MATLAB® Parallel Server™) or modify the license (if license manager is managing other products in addition to the server).

If Network License Manager Manages Only MATLAB Parallel Server Cluster

Disable the network license manager, and delete license.



  1. Start your current LMtools.exe.

  2. Navigate to the Start/Stop/Reread tab and choose Stop Server.

  3. Navigate to the Config Services tab and choose Remove Service.

  4. Close out of the current LMtools.exe.


  1. Run lmdown.

  2. Delete the existing network license manager by deleting the entire folder where you previously placed the license manager binaries.

If Network License Manager Manages Multiple Products

Modify the license to remove MATLAB Parallel Server.

  1. Shut down the network license manager.



    In your current LMtools.exe, navigate to the Start/Stop/Reread tab and choose Stop Server.


    Run lmdown.

  2. Open the MathWorks license file for editing:


    The exact name of your license file and its location might vary. If you have trouble finding the license file, see Article Where are the license files for MATLAB located?

  3. In the license file, locate and remove the entry that begins with the text:

    INCREMENT MATLAB_Distrib_Comp_Engine ...

    The entry might span more than one line in the file. Remove the entire entry and save the file.

  4. Restart the network license manager for the license file change to take effect.

    Network license manager utilities – such as lmstat – can verify that only the proper products are licensed. To use the lmstat function, open Terminal and run the following commands:

    cd $MATLABROOT/etc/glnxa64
    ./lmutil lmstat -a
