Hi,
The two most common causes of License Manager Error -9 are:
  • The MATLAB license file was activated for a different computer and/or user account
  • You have a Designated Computer MATLAB license and MATLAB is already running under a different user account on this computer
MATLAB was activated for a different Computer and/or User Account
More specifically, this means that the host ID specified in the license file is not the host ID of the computer. If you are using an Individual license, this may also indicate that the login name specified in the license file does not match the logged-in user account.
To resolve this issue, you need to reactivate MATLAB using the correct host ID/Username:
What is a Host ID? How do I find my Host ID in order to activate my license?
How do I find my Login Name in order to activate my license?
How do I activate MATLAB?
