When installing MATLAB or other MathWorks Products, MATLAB automatically activates itself either during installation (R2020a and newer) or after the installation (R2019b and older). The activation client does not need to be launched manually nor will it appear for R2020a and newer.
However, it may be necessary to activate MATLAB manually. There are two ways to activate MATLAB:
  • Automatically activating using the activation client
  • Manually activating through the MathWorks License Center

Automatically activating using the activation client

It is sometimes necessary to activate an instance of MATLAB which is already installed. For example, you may need to update your license, or you may need to change the license that MATLAB is using.
To activate an instance of MATLAB which is already installed on an online machine, launch the MathWorks activation client. There are two ways to do this:
If you can launch MATLAB:
If MATLAB is currently activated and able to launch, you can launch the MathWorks activation client from the MATLAB help menu:
  1. In the "Resources" section of the toolstrip, open the "Help" menu.
  2. Hover over the "Licenses" submenu.
  3. Click "Activate software." This will launch the MathWorks activation client.
If MATLAB will not launch
If you have an expired or otherwise unusable license, MATLAB may not be able to launch. In this case, you will need to launch the MATLAB activation client directly. The location of the MathWorks activation client depends on your Operating System and MATLAB release.
For R2022b and newer:
Windows
The activation client is located below. You will need to replace R20XXx with your release of MATLAB, such as R2022b.
C:\Program Files\MATLAB\R20XXx\bin\win64\MathWorksProductAuthorizer.exe
 
macOS
  1. Open Finder.
  2. Go to "Applications".
  3. Right-click or control-click on the MATLAB application icon. (e.g. MATLAB_R2022b.app)
  4. Click on "Show Package Contents".
  5. Open the folder "bin", then "maci64".
  6. Find MathWorksProductAuthorizer and then double-click it to launch it.
 
Linux
The activation client is located here:
/usr/local/MATLAB/R20XXx/bin/glnxa64/MathWorksProductAuthorizer.sh
For R2022a and older:
Windows
The activation client is located here:
C:\Program Files\MATLAB\R20XXx\bin\win64\activate_matlab.exe
macOS
  1. Open Finder.
  2. Go to "Applications".
  3. Right-click or control-click on the MATLAB application icon. (e.g. MATLAB_R2022b.app)
  4. Click on "Show Package Contents".
  5. Open "Activate.app".
Linux
The activation client is located here:
/usr/local/MATLAB/R20XXx/bin/activate_matlab.sh
Once you have launched the MathWorks activation client:
  1. Select "Activate automatically using the internet."
  2. Log into your MathWorks account
  3. Select the license from the list of licenses you would like to activate
  4. Confirm the activation information
  5. Click "finish" to complete the activation process.

Manually activating through the MathWorks License Center

If you are on an offline machine, it may be necessary to activate the license through the MathWorks License Center.
Instructions on how to activate MATLAB via the license center are detailed in the article below:
