Hi Sanjay,
The best way to resolve a License Manager Error -9 is by reactivating MATLAB with the activation client. To do this, locate the activation client at C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe (assuming you are on Windows).
Once you have launched the MATLAB activation client:
- Select "Activate automatically using the internet."
- Log into your MathWorks account.
- Select the correct license.
- The username field should auto-populate with the correct user name. Leave it as is.
- Confirm the activation information.
- Click "finish" to complete the activation process.
- Restart MATLAB.
In case you are on MAC or Linux, please visit the detailed answer in this link. Hope this helps.
