When the installation successfully completes, you can choose to activate the software you just installed. You cannot use the software you installed until you activate it. Activating immediately after installation is the quickest way to start using MATLAB®. Click Next to proceed with activation.
If you choose to exit the installer without activating the software, clear the Activate MATLAB option and click Finish (the button label changes). Use the activation application to activate the software at a later time. If you have not activated the software, the activation application starts automatically when you start MATLAB.
