Hi, I recently purchase an individual license through my institution and installed Matlab (R2024a) on the cluster computer (Linux system) of our institution. To run heavy calculations, I need to request computation nodes through a slurm management system. However, I can not use my Matlab on the computation node, as I get the error message:

License checkout failed.

License Manager Error -9

The hostid of your computer ("......") does not match the hostid of the license file (......).

To run on this computer, you must run the Activation client to reactivate your license.

I assume I need to activate Matlab on the node computer everytime I run any scripts on it but I was also unable to run '.../R2024a/bin/glnxa64/MathWorksProductAuthorizer' as there is no available GUI for our cluster computer. I wonder where I could find the instruction on silent activation of license online as I have not found a complete instruction anywhere.

Any feedback or suggestions will be very helpful and much appreciated. I apologize for possibly not following the guideline as this is the first time I ask questions here. Many thanks.

Hi @Yi,

When installing and/or activating MATLAB, the MathWorks Installer and/or Activation Client will attempt to pull the username of the user installing MATLAB to activate. If the username was changed or the username pulled is incorrect, the username in the license file will not match the username of the MATLAB user, and MATLAB will provide a License Manager Error -9.

To resolve, verify the username of the MATLAB 'user', then reactivate MATLAB with the correct username. Please note that administrator accounts will have a different username, so you should ensure that you select the login name that corresponds to the username of the profile you plan to run MATLAB from.

Note: Usernames are case sensitive and may break with spaces.
