or see a similar error in the debug log file on the license server, then you are facing the license manager error 114. This error means that the license file used by the network license manager is incompatible with the MATLAB version you are trying to run. This can happen when the license file has been updated to a newer release but the license manager has not been updated. To fix this error, you need to upgrade the network license manager to the latest version available.
Steps to upgrade the network license manager
Download the latest network license manager from [MathWorks website].
Stop the license manager service on the license server. You can do this by using the LMTOOLS utility or by running the stop command in a command prompt.
Extract the downloaded file and copy the contents to the license manager installation folder, overwriting any existing files.
Restart the license manager service on the license server. You can do this by using the LMTOOLS utility or by running the start command in a command prompt.
Verify that the license manager is running and serving licenses by checking the status in LMTOOLS or by running the lmstat command.
Start MATLAB on your client machine and check if the error is resolved.

Troubleshooting tips
If you still see the error after upgrading the network license manager, make sure that you are using the correct license file. You can obtain a new license file from [MathWorks website] by logging in with your MathWorks account and selecting your license number.
If you are using an options file to control access to licenses, make sure that you have added your computer name or user name to the appropriate group. You can edit the options file using a text editor and restart the license manager service for the changes to take effect.
If you are using a firewall on your license server or client machine, make sure that it is not blocking the communication between them. You may need to open some ports or allow some programs through your firewall settings. For more information on firewall configuration, please see [this article].
If none of these tips help, you can contact [MathWorks Support] for further assistance.
