Hi Sanjay,
The best way to resolve a License Manager Error -9 is by reactivating MATLAB with the activation client. To do this, locate the activation client at C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe (assuming you are on Windows).
Once you have launched the MATLAB activation client:
- Select "Activate automatically using the internet."
- Log into your MathWorks account.
- Select the correct license.
- The username field should auto-populate with the correct user name. Leave it as is.
- Confirm the activation information.
- Click "finish" to complete the activation process.
- Restart MATLAB.
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:
- In the "Resources" section of the toolstrip, open the "Help" menu.
- Hover over the "Licenses" submenu.
- 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
- Open Finder.
- Go to "Applications".
- Right-click or control-click on the MATLAB application icon. (e.g. MATLAB_R2020b.app)
- Click on "Show Package Contents".
- 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:
- 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.
