File Installation Key
A File Installation Key identifies the products you can install. You must use a File Installation Key for installation if you do not have an internet connection. The MATLAB® administrator can retrieve the File Installation Key from the License Center at the MathWorks® website.
Using a File Installation Key requires you to run the installer from either:
A MATLAB DVD.
A folder that includes the installer and the product files.
The MATLAB administrator can run the installer to download the required files to this folder.
