When installing MATLAB or other MathWorks Products, the license will activate itself either during installation (R2020a and newer) or after the installation (R2019b and older).
However in some cases it may be necessary to activate MATLAB directly. There are two ways to activate MATLAB:
  • Manually activating through the MathWorks License Center
  • Automatically activating using the activation client
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:
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:
Windows
The activation client is located here:
C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe
Mac
  1. Open Finder.
  2. Go to "Applications".
  3. Right-click or control-click on the MATLAB application icon. (e.g. MATLAB_R2020b.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.
If you are continuously prompted to activate MATLAB every time you launch it, please see this article:
A video walkthrough on how to install and activate an individual license can be found below:
If you are unable to activate MATLAB after following the instructions in this article, please contact MathWorks support:

You can do put a "." at the beginning of the command to run it in Terminal. I.E.
./usr/local/MATLAB/R20XXx/bin/activate_matlab.sh

./usr/local/MATLAB/R20XXx/bin/activate_matlab.sh
No, that will not work unless your current directory happens to be /
Instead,
sh /usr/local/MATLAB/R20XXx/bin/activate_matlab.sh

Hi, I have a windows 10 and I was wondering where exactly do you put the code in for the activation client?

For Windows 7 64 bit the location of activate is located in C:\Program Files\bin\win64 not C:\Program Files\MATLAB\R20XXx\bin\winXX, at least on my machine

Yes, you can run the activation client again.

You follow the instructions in the main answer, which is broken down by operating system and broken down by whether you are able to start MATLAB or not.

I am getting error although I followed this procedure correctly. The error information is given below:
Diagnostic Information:
Feature: SR_MATLAB
License path: (Some Place)/.matlab/R2015b_licenses:/usr/local/MATLAB/R2015b/licenses/license.dat:/usr/local/MATLA

Licensing error: -9,57.

It would have been helpful if the activation manager made it explicit that it requires my local machines user id and not the one I created during the registration for matlab.

It could be that it can not find the microphone use the RCA or Computer connection and open the sound icon in the controll panel

I find some Linux related posts that relate SR_MATLAB to ethernet ID problems, but I have never seen any hint that microphones have an influence on licensing ??

We will need more information than that. What error message are you encountering? Which version of MATLAB are you working with, and which operating system? Do you have a direct connection to the Internet or are you working through a proxy server?

Just a quick edit for those in Ubuntu 16.04. If I go to the location described and right-click on the folder then "Open in Terminal" then type in "activate_matlab.sh" you will get a "command not found error"
How need to right-click within the folder and then type sudo ./activate_matlab.sh

Right click. Open in terminal. then sudo ./activate_matlab.sh
Didn't help me at all. I wonder if that is because when this was a win10 machine it had matlab on it. If so matlab is screwing this up.

Patrick did specifically say "Just a quick edit for those in Ubuntu 16.04"
For Windows you would see the information posted by Mathworks, above, directing you to
C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe
for current versions that would be
C:\Program Files\MATLAB\R20XXx\bin\win64\activate_matlab.exe
but sufficiently old versions might use win32

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. To find the MATLAB activation client on each OS:
Windows
The activation client is located here:
C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe Once you have launched the MATLAB activation client:
Select "Activate automatically using the internet." Log into your MathWorks account Select the license from the list of licenses you would like to activate Confirm the activation information. Click "finish" to complete the activation process.
Thanks! It works perfectly...

What to do when activate_matlab.exe does not open / fails silently?
Win7/64, MATLAB 2018b, used to work fine.

Look in "C:\Program Files\MATLAB\R2019a\bin\win64" since you're using a 64 bit version of Windows.

What if the activation is not even in the Win64 , having Windows 10?
I keep doing the activation over and over again. It keeps going to the same Admin window

  2. Log into your MathWorks account.
  3. Select the correct license.
  4. The username field should auto-populate with the correct user name. Leave it as is.
  5. Confirm the activation information.
  6. Click "finish" to complete the activation process.
  7. Restart MATLAB.

If you've gone through the steps in this MATLAB Answers post and MATLAB is still not able to activate successfully please contact Technical Support using the telephone icon in ther upper-right corner of this page and work with them to determine how to get MATLAB working successfully.
