If MATLAB is still installed
To deactivate MATLAB:
- Launch MATLAB.
- Click on "Help" in the MATLAB toolstrip, right beneath the question mark in the white circle. (Click on the "Home" tab if you don't see the help menu.)
- Hover over "Licensing."
- Click on "Deactivate Software..." from the licensing submenu and follow the on-screen instructions.
In MATLAB R2012a and earlier there is no toolstrip, so the Licensing submenu is in the Help menu.
In MATLAB R2007b and earlier, activation and deactivation do not apply.

On Windows, the deactivation client remains on the computer even if MATLAB has been uninstalled. Assuming MATLAB was installed in the default location, the deactivation client is located here:
