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.

This may be a lame answer but I just needed to close MatLab and give my slow computer a minute to think, then it seemd to work. Though I would share as I did get to this page looking for an answer

I had the same issue. Deleting an exe file which was on my matlab path solved the issue.(Linux Ubuntu distribution )
