Why am I still being prompted to close all MATLAB sessions during an installation process after I have already closed MATLAB?

I would like to know how I am able to install without the following error message:
There is a session of MATLAB running on this machine. In order to complete this installation you must close all running MATLAB sessions.
I closed all running MATLAB sessions and I checked there are no MATLAB processes in the Windows Task Manager.

This error typically occurs when installing or updating MATLAB or other MathWorks products because there is a matlab.exe process running somewhere on the machine.
To resolve this issue, check all processes (from all users) to see if there is a matlab.exe running in the background before continuing.
If you cannot find any matlab.exe running and you receive this message, try restarting the computer before attempting the installation again.
