MATLAB: Am I still being prompted to close all MATLAB sessions during an installation process after I have already closed MATLAB

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.

Best Answer

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.

MATLAB: Does starting MATLAB from the desktop shortcut or start menu fail saying MATLAB is not found

If the MATLAB shortcut or start menu entry that is created by the installer indicates that the matlab.exe cannot be found, antivirus may have quarantined or deleted the matlab.exe file. To find out for certain, open your antivirus software and check for any recent notifications or actions that your antivirus has taken on your computer.

You can also check to see if MATLAB will start if you find and execute the matlab.exe file directly. To find where your installation of MATLAB has the matlab.exe file, right click on the desktop shortuct or start menu icon and click on "properties". Check the 'target' field for the location of matlab.exe. Note that most MATLAB versions put the matlab.exe file in the bin folder where you chose to install MATLAB. Browse to this file and see if it is present. If it is, try double clciking on it. If it is not there or continues to say that the file is not found, then it is likely the file has been quaranteened or deleted by your anitvirus.

For further assistance on configuring your antivirus, contact your IT department or anitvirus manufacturer.

MATLAB: How to detect how many instances of Matlab are currently running on the machine

You can call the "tasklist" (DOS) function with some arguments that will tell you how many are running on the system. You can then parse the return and get a count.

e.g.:

>> [status,result] = system('tasklist /FI "imagename eq matlab.exe" /fo table /nh')
status =
       0
result =
MATLAB.exe                    5132 Console                    1    359,184 K
MATLAB.exe                    6028 Console                    1    358,908 K
