Why are my add-ons and toolboxes not uninstallable?

I've been following the documentation to uninstall some toolboxes/add-ons from the MATLAB infrastructure I manage.

Initially, I used matlab.addons.installedAddons which returned two values as expected - "MATLAB Coder" and "Signal Processing Toolbox". When I then ran matlab.addons.disableAddon or matlab.addons.uninstall I was presented with the error "not supported for MathWorks products, MathWorks toolboxes, or support packages".

I then tried using matlab.addons.toolbox.installedToolboxes with a view to using matlab.addons.toolbox.uninstallToolbox, however the first command returns empty values so I can't uninstall using that method.

I'm completely limited to the command line (ubuntu 20.04) so I can't open matlab and uninstall from the UI unfortunately. I feel that this may be a bug as I don't see how my products don't fall under either the add-on or toolbox banner, but I'd be grateful for the thoughts and advice of the community. My MATLAB version is r2021a.

Hello,

I understand that you are having trouble uninstalling the add-ons and toolboxes.

Here are the few steps that you can follow for uninstalling MATLAB add-ons and toolboxes:

• To uninstall a Toolbox: Use this command.

matlab.addons.uninstall(‘Toolbox Name’); 

• To uninstall a Specific version of Toolbox: Use this command.

matlab.addons.uninstall(‘Toolbox Name’, ‘version number’);

• To uninstall an add-on: Use this command.

matlab.addons.uninstall(name);

Please refer the documentation link below for uninstalling MATLAB addons and toolboxes:

Uninstall add-on - MATLAB matlab.addons.uninstall (mathworks.com)

Thanks

I also could not uninstall Matlab Toolbox (tried twice using GUI and the uninstall finished but as Matlab restarted, the Toolbox was still there).

Your instruction did not work.

>> matlab.addons.uninstall("Deep Learning Toolbox");

Error using matlab.addons.uninstall (line 106)

Using matlab.addons.uninstall to uninstall MathWorks products and support packages is not supported.

I'm facing the same issue. As noted by Trong, when I try to uninstall a given addon, I recieve the error:

>> matlab.addons.enableAddon("DM")

Error using enableAddonWithNameOrIdentifierAndVersion (line 96)

Enable/Disable not supported for MathWorks products, MathWorks toolboxes, or support packages.

Error in

matlab.addons.enableAddon (line 44)

enableAddonWithNameOrIdentifierAndVersion(NameOrIdentifier);

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The error is vague and apparently this is the only thread I could find online that even mentions this error... it would be great if a matlab representative gave this issue a closer look...

I have exactly the same problem with MATLAB 2026a under Debian. Unistall using the Add-on Manager claims to uninstall, restarts and toolbox is still there. Using the MATLAB console gives the same errors as mentioned above. "installedToolboxes" is an empty struct, although the toolboxes are definitely there. I am lost. I really don't want to delete the MATLAB installation and reinstall. Why are thesimplest things in MATLAB sometimes so buggy?
