Hello Pierre,
I see that you are facing License related error while trying to install MATLAB on a server
Please note that, this error can occur when the license file used by the network license manager has been updated to a newer Release but the license manager has not been updated.
To resolve this, upgrade the network license manager to the latest version available. For instructions on this process, please see the link below provided by MathWorks Support Team:
I hope it helps!
