Throughout the term of your license, your MATLAB® installation periodically contacts MathWorks® to verify that your license is up to date. If your license is up to date, the validation process is transparent. If it determines that you need to update your license, the validation process displays a dialog box giving you the option to update your license.
You can disable validation in the License Center at the MathWorks website.
To update your license manually from within MATLAB:
On the MATLAB toolstrip in Resources, click the down arrow under Help.
Select Update Current Licenses... and follow the prompts to update your license.
If your license file has expired or another licensing requirement is preventing MATLAB from starting, you can update your license by using the MATLAB activation client.
For instructions on using the activation client, see Activate MATLAB Installation Manually.
If the computer that is running MATLAB cannot connect to the Internet, you can download a license file manually from the MathWorks website on another computer and move the file to the target computer.
