Why does the installer tell me I have entered in an invalid File Installation Key when installing using my MathWorks account or activation key?

I am instaling my MATLAB automatically using the Internet. When I log into my MathWorks account or provide my Activation Key, I get the error message:

ERROR: File Installation Key Error: You have entered an invalid File Installation Key.

How do I proceed beyond this error.

This error means that there is an invalid installation key for your license. The installer will retrieve the File Installation Key MathWorks during the automatic installation process even though you may not have entered this key. If you are selecting a MATLAB Online Trial license, you will get this error as there is no File Installation Key to retrieve.

If you know you have the correct File Installation Key, make sure there are no invalid characters being entered into the field. This can occur if the File Installation Key is copied and pasted with invisible and/or special characters. If possible, try entering your File Installation Key by hand.
