Why do I receive an error about an invalid File Installation Key when installing MATLAB manually without the Internet?

When installing MATLAB manually without the Internet, I provided the File Installation Key provided by the MathWorks. When I enter the File Installation Key the installer tells me that it is invalid. How can I install my MATLAB manually without the Internet?
