If you are looking to purchase a license or start a trial, view the link below.
This error is caused due to the use of an incorrect Activation Key within the installer including
  • If you are using an Activation Key that is invalid. Please use the correct Activation Key in order to activate MATLAB.
    • Unless you are trying to link your MathWorks account to a new license, you do not need an Activation Key. If you are not tied to any licenses, please either contact your organization to be tied to a license or purchase one.
  • If you are using an Activation Key for a license that is Login Named User (LNU) only.
  • If you are trying to log into an LNU prompt with an account that does not have an LNU license.
Login Named User (LNU) is a portable license option that verifies license rights over the internet and requires users to log into their MathWorks Account each time they start MATLAB. As such, LNU requires an uninterrupted internet connection.

In R2012a, serial numbers were still used instead of Activation Keys. You should contact Mathworks Support if you need assistance in finding your serial number.
