Why does my MATLAB installation fail at "post-installation tasks" or hang indefinitely?

When installing MATLAB, the installation gets to 99% or 100% but then hangs at "post-installation tasks" and does not complete, or pop-up with an error. How can I finish the installation?

First, try to run the "matlab" executable from the /bin directory within your MATLAB installation directory.

If you get errors when running MATLAB, try to run the following in Terminal depending on your operating system, while specifying your actual MATLAB installation directory path and replacing "R20XXy" with your actual release:

Windows (in cmd running as adminstrator)

"C:\Program Files\MATLAB\R20XXy\bin\win64\registerWithOS.exe"

Linux

sudo /usr/local/MATLAB/R20XXy/bin/glnxa64/registerWithOS.sh

macOS (Intel)

sudo /Applications/MATLAB_R20XXy.app/bin/maci64/registerWithOS

macOS (Native Apple Silicon)

sudo /Applications/MATLAB_R20XXy.app/bin/maca64/registerWithOS

On Windows, this also creates a Start Menu shortcut for MATLAB if you did not have one already, so you should be able to launch MATLAB from the Start Menu.

Check whether MATLAB now launches without error.

If you are still having issues after trying the above, try to perform a clean reinstallation of MATLAB.
