Update Network License Manager Software

Updating the network license manager software requires you to stop and then restart the license manager. You must be a network license administrator to perform this procedure.

To avoid any potential issues with license file operation, consider upgrading the network license manager software whenever you upgrade MATLAB® software.

Step 1. Stop Network License Manager

If the network license manager is running, shut it down.

  • Linux® and macOS Systems — Use the lmdown command. For additional information, see Using Command-Line Utilities.

  • Windows® Systems — Remove the existing service to prevent any conflicts.

    1. Start LMTOOLS by double-clicking the lmtools.exe file in the matlabroot\etc\$ARCH folder, where matlabroot is your MATLAB installation folder and $ARCH is a platform-specific subfolder, such as win64.

    2. Select the Config Services tab.

    3. From the Service Name menu, select the service you want to remove, and click Remove Service.

Step 2. Select Installation Method

You can choose to download only the software daemons or use the MATLAB installer to update the network license manager.

Update Network License Manager Software with Daemon Download

If you already have the network license manager installed and configured, you can download new network license manager daemons directly to your server instead of using the MathWorks® installer to install the latest version of the software. The license manager daemons include:

  • lmgrd — Network license manager daemon

  • mlm — MathWorks vendor daemon

  1. Stop the network license manager as described in Step 1.

  2. Download the ZIP file for your platform from License Manager Download on the MathWorks website.

  3. Extract the files from the ZIP file to the network license manager folder. The default location for the license manager files is the matlabroot\etc\$ARCH folder, where matlabroot is your MATLAB installation folder and $ARCH is a platform-specific subfolder.

  4. Restart the network license manager, and configure it as needed.

Update Network License Manager Software Using MATLAB Installer

  1. Stop the network license manager as described in Step 1.

  2. Install license manager software update. Follow the procedure in Install License Manager on License Server.
