If you are looking to purchase a license or start a trial, view the link below.
This error is caused due to an issue with the Activation Key, which could be caused by one of the following:
  • 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.
  • If you are attempting to link to an Individual license that already has an end user.
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.

The volunteers who answer questions here do not have access to the license database. Also, the license terms say that we can only make available the licenses that we do have to other people in the same organization that we are in -- so if I had a spare license, I would not be permitted to let you use it.
You need to contact the place you got your license from -- your university or your employer, or Mathworks Sales if you bought from Mathworks.
