Option 1: Using the Toolstrip

Launch the Support Package Installer from your version of MATLAB and navigate to the correct support package.

Option 2: "Get Support Package" Button (.mlpkginstall file*)

Clicking the Get Support Package button provides the support package install file:
([filename].mlpkginstall)

There are several ways to initiate the Support Package Installer from these files:

• Open the .mlpkginstall file directly from your Internet browser.
• Download and save the file (the default option for some Internet browsers), and open it directly from your Windows, Mac, or Linux operating system.
• Open the .mlpkginstall file directly from within MATLAB by navigating the Current Folder to the location of the downloaded file and double clicking it. That will initiate the installation for the MATLAB release that you have open.

The primary difference between using the .mlpkginstall file (option 2) rather than the toolstrip (option 1) to initiate support package installation is that the file allows the user to avoid the support package selection screen on the installer.

*These file types were introduced in MATLAB R2013a.
