Hi,

Regarding the License Manager Error -9 you have encountered, following response by MathWorks Support Team could be helpful:

https://www.mathworks.com/matlabcentral/answers/99067-why-do-i-receive-license-manager-error-9#answer_108414

As stated in the article, this error occurs when the OS username of the user launching MATLAB does not match the username that was used during activation. To resolve this error, you need to verify the Host ID of the machine, then reactivate MATLAB.

Also, with Designated Computer licenses, MATLAB can only be running by one user account on the machine at a time. If there is already a MATLAB process running under a different user, MATLAB issues License Manager Error -9.

I hope the information provided above is helpful.
