The best way to resolve a License Manager Error -9 is by reactivating MATLAB with the activation client.

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_R2015b.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 MATLAB activation client:

1. Select "Activate automatically using the internet."
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.

Still seeing a License Manager Error -9?

• The username in the license file does not match
• The Host ID in the license file does not match
• You have a Designated Computer MATLAB license and MATLAB is already running under a different user account on this computer.

Confirm your Username and Host ID using the activation client:

1. Run the activation client and select "Activate manually without using the Internet."
2. Choose “I do not have a license file. Help me with the next steps.”
3. Copy your Host ID and Computer Login Name.
4. Click the back arrow 2 times and choose “Activate automatically using the Internet” then input the appropriate username.
5. Launch MATLAB using the appropriate user account.

Activation client requires elevated privileges to run? Connection error when Activating automatically? Still seeing a License Manager Error – 9?
