I am trying to activate and use MATLAB. Every time I start MATLAB, it prompts me to activate, even though I complete the process and it states activation is complete each time.

Why am I continuously prompted to activate when I try to launch MATLAB?

When launching MATLAB, you will be prompted to activate if no valid license files can be found on the license file search path. The most common reasons that MATLAB will continuously prompt you for activation are:

  • Activating to the wrong computer login name (username)
  • Insufficient user privileges
  • Wrong file type
  • Activating to an expired or invalid license file

Activating to the wrong computer login name (username)

For Individual licenses, the MathWorks Installer and Activation Client will attempt to place the license file into the directory of the user specified. If the user specified is not the user attempting to launch MATLAB, then MATLAB will not be able to locate the license file. This is most commonly seen when administrator credentials are used to install or activate due to to limited user permissions, and as a result, the license file is stored under the administrator account.To resolve this, verify the username of the MATLAB user, then reactivate MATLAB with the correct username.

Insufficient User Privileges

When activating MATLAB, you must have sufficient user privileges to create the required licenses folder and create the license file. To verify that the license file is being created, browse to the location where the license files are stored for your license option and operating system type:
