Hi @Henrik,

This error path (/usr/MATLAB/...) suggests you’re on Linux or macOS. On Windows, similar errors happens when MATLAB is install into C:\Program Files\MATLAB without admin rights. In that case, run the installer as administrator.

To resolve this issue try the given below steps, these might help in getting started:

• Open a terminal and run the installer with "sudo".

sudo ./install

• If you downloaded an installer script:

sudo sh install

This gives the installer the necessary permissions.

During installation, make sure you are installing to a directory where you have write access. By default, MATLAB wants to install to /usr/local/MATLAB or /usr/MATLAB. If you don’t have root access, choose a directory in your home folder (e.g., /home/yourusername/MATLAB/R2025a).

If the installer is trying to modify or overwrite /usr/MATLAB/R2024b, and you don’t need that version anymore, you can remove it (with admin privileges).

sudo rm -rf /usr/MATLAB/R2024b

Hope this helps!

/usr/local/MATLAB strongly hints that this is a linux installation.

/usr/local/MATLAB is not impossible for a MacOS installation, but the MacOS installer automatically requests authentication for permission to install, and installation by default is to /Applications/

I also had this error while trying to install MATLAB 2025b Update 2.

I solved it by simply changing the user group of the MATLAB directory and all its subdirectories with this command:

sudo chown -R your_username:your_username /usr/local/MATLAB/

This operation must obviously be performed with MATLAB closed.

To find your_username, use the

whoami

command.

I recommend this operation only if you have some experience with Linux.

The file permissions, however, do not need to be changed; they are already correctly set to 755 by default.

I hope this helps MATLAB users on Linux.
