Add-on Product Installer Error "Something Unexpected Occured"

While I was installing add-ons (Image Processing Toolbox and Communication Toolbox), after some time

" Something Unexpected Occurred

To resolve this issue, contact Technical Support" shows up at the installer and cancels the installation. Why this happens and how I can solve it?

Edit: I downloaded the MATLAB installer from the website, chose the toolboxes I want and started the installation. I didn't choose the packages/toolboxes I already have installed.

HI,

If you are receiving this error when installing any support package in MATLAB R2016b, apply the following patch to your MATLAB installation (instructions included): www.mathworks.com/support/bugreports/1507667

If you are still experiencing this error after trying the above, locate your MATLAB installer log file. For more information on locating your installer log file, please reference this article:Where are the MATLAB installation log files located?

If you need further assistance, please contact MathWorks support and attach your MATLAB installer log file.

I am getting the same error in 2019b release. Is the same patch applicable?

[Marie Pape]

I am also getting this error on the 2019b release.

Hi, I got this error in 2019b on Linux Ubuntu 19.10 when adding a toolbox.

After going through the log files, I found that it is due to the Matlab installer making a mess of the permissions and installation pathways.

I gave my user account full permission over matlab directories in Linux.

Assuming you used the default install directories when installing Matlab, you can fix it as following in the Linux terminal:

sudo chown -R myusername /usr/local/MATLAB/R2019b

you may also need to do:

sudo chown -R myusername /home/myusername/.matlab/R2019b

Would be cool if Mathworks could get things right out of the box, instead of leaving the users to sort these things out. A Matlab install in Linux seems to take the best part of half of day of troubleshooting, as well as setting up symbolic links, etc.

Thanks for that hint. It worked for me, too.

[Andreina Rascon]

This worked for me, I have Ubuntu 18.04 and matlab 2019b

Yeah, same problem for me also. How to solve this in WINDOWS 10 pc for R2019b?

[Zeliha YILDIRIM]

Thanks, it worked :)

[Agathe Jouneau]

@Bryan Thanks a lot! It also worked on Mac for me with the command:

sudo chown -R myusername /Applications/MATLAB_R2020b.app

[Jerusalem Teklu]

Thank you so much @Agathe Jouneau!! It works for me (ubuntu R2022b) as well.
