Version: R2024a

I can successfully install other Add-Ons, but when I install "Signal Processing Toolbox". After downloading for a while, it stopped reporting errors.

ERROR: "Something unexpected occurred. Try rerunning the installer"

Please see the suggestions in this answer: https://www.mathworks.com/matlabcentral/answers/101885-how-do-i-install-additional-toolboxes-into-an-existing-installation-of-matlab

I recently had a similar issue and ended up rerunning the installer. When prompted, you only need to select the toolboxes you want to add to you existing install. You do not need to reinstall products that are already on your computer.

在 MATLAB Online 中打开

@Georgios run this in the command window, or as a script file, and tell us what it says:

% Check that user has the specified Toolbox installed and licensed.
% hasLicenseForToolbox = license('test', 'image_toolbox');	% Check for Image Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Image_Acquisition_Toolbox');	% Check for Image Acquisition Toolbox.
% hasLicenseForToolbox = license('test', 'Statistics_Toolbox');	% Check for Statistics and Machine Learning Toolbox.
hasLicenseForToolbox = license('test', 'Signal_Toolbox');	% Check for Signal Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Video_and_Image_Blockset');	% Check for Computer Vision System Toolbox.
% hasLicenseForToolbox = license('test', 'Neural_Network_Toolbox');	% Check for Deep Learning Toolbox.
if ~hasLicenseForToolbox
    % User does not have the toolbox installed, or if it is, there is no available license for it.
    % For example, there is a pool of 10 licenses and all 10 have been checked out by other people already.
    ver % List what toolboxes the user has licenses available for.
    fprintf('Sorry, but you do not seem to have the Signal Processing Toolbox.\n');
else
    fprintf('You do have a license for that toolbox, but it may be not installed correctly.\n')
end

If you rerun MATLAB installer using sudo, it does not give you the option to select additional tools and if you try to rerun the installer as normal user, you can't install on the same location.

You should not suggest something, you have not tested.

From the very first post: "I recently had a similar issue and ended up rerunning the installer."

However, I only ran it on my machine, which is running Windows 11, via the setup UI. i did not test on all possible operating systems, and did not test all possible ways of running the installer.

It does not surprise me that installing from the command line gives a different experience.
