MatlabR2016b uninstaller won't work

I installed a more recent Matlab version (R2019b). I was trying to uninstall MatlabR2016b from my notebook as I woud usually do from the control panel. As soon I as click on uninstall, the uninstaller crashes at 0% without any error message or anything like it. Is there another way to do so?

I have the exact same problem. How did you solve this?

I tried 3rd party remover programs - not working.

Manually using the unnstaller - not working.

My last resort is fully resetting my laptop but that will give me such a hassle just for a program that does not want to uninstall.

To this day, I'm still not able to unistall the R2016b version, not even with a third party remover program. I just uninstalled the more recent one waiting for a solution.

I have the same problem (on Windows 10), wanted to install a new version of Matlab and remove 2016b before doing so. Uninstaller crashes to desktop without error messages after a few seconds at 0%. I was however able to remove all toolboxes, including Simulink, using the uninstaller, and have only the main program remaining. The uninstaller still crashes to desktop, but now makes it to 1%!

same problem too i've installed R2020a, (windows 10 R2016a) i've deleted all toolboxes and simulink, crash at 1%.

What if you try to delete it without before had install a new version of matlab?

@Johannes Eichholz & @zini giacomo I've done as you said and now I've got the same problem...? It's so frustrating!

After I installed the more recent version and realised I had this problem with the 2016b version, i uninstalled the recent version (not sure which one it was, maybe 2019b), which gave me no problem whatsover, and then proceeded to uninstall 2016b, whose uninstaller crashes (at 0% before, now 1% after I removed all the tools).

EDIT: by scrolling the internet I've found this software (Geek Uninstaller) which forces the removal of the program files. It looks like it worked.

it didn't work for me

I have also faced this same problem.

I deleted the whole Mathwork folder (I had only one matlab) as suggested from this link:

********************************************************************

If the MATLAB uninstaller was unable to complete, try executing the uninstall.exe from $MATLAB\uninstall (where $MATLAB is the folder where MATLAB is installed). For example:

C:\Program Files\MATLAB\R2014a\uninstall\bin\win64

If you are unable to complete the uninstaller, you can try the following workarounds:

1) Re-install MATLAB and overwrite the current MATLAB folder. This will re-create uninstall.exe and should allow you to uninstall once complete

2) Manually delete the MATLAB installation folder.

Aside from removing the installation of MATLAB, you can remove the MATLAB entries from the Windows System Path. For help modifying the Path in Windows, see the related article:

"How do I set my system path under Windows"

Further I follewd the procedure listed here:

********************************************************************

2. Delete the user preferences directory

In a File Explorer window, type the following into the address bar and then press Enter:\n

%appdata%

This solved the problem for me. I am not sure whether this may work for you.

Thank you.
