Manage Your Licenses
You can manage many licensing-related tasks, such as activating licenses, deactivating licenses, or updating licenses, through MATLAB® or your MathWorks® Account on www.mathworks.com.
Some options for license actions require an internet connection. If your internet connection requires a proxy server, use MATLAB web preferences to specify the server host and port. See Specify Proxy Server Settings for Connecting to the Internet for more information.
Update Current Licenses
The simplest way to update your license file is from within MATLAB. You should perform this task within your MathWorks Account only if you cannot access MathWorks from your computer. For additional details on updating licenses, see Update Your License, or, if you are a license administrator, see Update Network License.
On the Home tab, in the Resources section, click Help > Licensing > Update Current Licenses.
MATLAB displays a list of all your MathWorks licenses on this computer, with their status. When you select a license and click Update, MATLAB contacts MathWorks to retrieve the most current version of the License File for the license. The update process overwrites the current License File on your system. You need to restart MATLAB.
MathWorks retrieves the most current version of the License File for the license. You need to restart MATLAB.
The simplest way to activate your software is from within MATLAB. You should perform this task within your MathWorks Account only if your computer cannot communicate with MathWorks. For additional details on activation, see Activate MATLAB Installation Manually.
On the Home tab, in the Resources section, click Help > Licensing > Activate.
MATLAB starts the activation application, which walks you through the activation process. Answer the questions on each dialog box, select the license you want to activate, and click Activate.
Although you can deactivate the software from within MATLAB, if you cannot access the computer to deactivate, you can still deactivate the software from your MathWorks Account.
For more details on deactivating MathWorks software, see Deactivate Your Installation.
On the Home tab, in the Resources section, click Help > Licensing > Activate > Deactivate.
MATLAB displays a list of all your MathWorks licenses on this computer, with their status. When you select a license and click Deactivate, MATLAB deactivates all releases on this computer associated with the license, and updates the licensing information at the MathWorks website. You will not be able to use MathWorks software with that license on this computer.
If you are not connected to the Internet, MATLAB deactivates the licenses on your computer but cannot update the corresponding license information stored at the MathWorks website. In this scenario, MATLAB returns a deactivation string. To complete deactivation, save a copy of this string, go to a computer with an internet connection, and visit the License Center at the MathWorks website. There you can sign in to your MathWorks Account and enter the deactivation string.
MathWorks deactivates all releases on the specified computer, and updates the licensing information in License Center.
Link a License to Your Account

If you are linking a network license, you may need to get the license number from your organization's license administrator.
