Update MATLAB (Faculty/Staff ONLY) All Platforms

Please note the following instructions can only be performed by you if you have access to an administrative account on your machine. If you do not have administrative rights to your machine currently and would prefer to do the update yourself please contact us via the helpdesk@econ.duke.edu. If you would prefer a technician to do the update for you please contact us via a ticket and we will contact you and schedule a convenient time for both to perform the update.

If you would like to update to the latest release or do a first-time install of MATLAB R2022a yourself, follow the link below to OIT’s software downloads.  The License update process requires you to have administrative rights.

Renewing MATLAB if your license has not yet expired and you can launch the program

The license expires on September 1 of every year.  OIT software licensing posts notifications on its blog and also sends out an e-mail to its email list when the license has been renewed with the MathWorks. If you need to renew your software, follow the instructions below.

For R2007a and later:

You must be logged into your computer as an administrator.

  1. Launch MATLAB. (If you are using Windows, you MUST launch MATLAB as an administrator by right-clicking the program and selecting the option to Run as Administrator)
  2. On the Home tab, Go to Help (look for the ? icon) -> Licensing -> Update Current Licenses and click Update.
  3. Once the license is updated, you must restart MATLAB.

Alternate instructions for Mac users: Right-Click your MATLAB application and select Show Package Contents.  Run Activate.app

 

For R2007b and earlier:

  • For a Windows installation:

For MATLAB R14 through R2007b you will need the PLP to update MATLAB. 

  1. Start the MATLAB Installer from the MATLAB CD or downloaded installation files (be sure to have downloaded each product file that is on your license, in addition to the installer itself).
  2. Select "Enter a new Personal License Password (PLP) to update your license without installing anything" rather than the "Install" option, and click Next.
  3. When prompted, enter the PLP and follow the installer's directions until it is complete.
  • For a UNIX/Linux/Mac installation:

For releases prior to R2008a, you will need the license file for your release of MATLAB in order to update MATLAB. 

  1. Locate your existing license.dat file in $MATLABROOT/etc (where $MATLABROOT is your MATLAB installation directory) and rename the file license.old
  2. Open license. old with a text editor.
  3. Remove all the lines in the file except for the lines that begin with SERVER and DAEMON.
  4. Paste the license information above the license file into this file.
  5. Save the new file as license.dat
  6. After you save the file, you will need to restart the license manager on Unix and Linux machines
