Sometimes support packages become corrupt and cannot complete installation or encounter errors that you cannot get past. In these scenarios, it is beneficial to perform a clean re-installations of your Support Package rather than a regular re-installation. To do this, follow these steps:

For R2016b and newer

1. Open MATLAB and choose the drop-down menu for "Add-Ons", followed by the "Manage Add-Ons" option. Find your Support Package on the generated list and click the "Uninstall" button across from it. Once this uninstall is complete, close out of MATLAB.

2. Navigate to the following folder on your computer and delete the contents you find there:

Windows = C:\ProgramData\MATLAB\SupportPackages\R20XXx\
Mac = /Users/<username>/Documents/MATLAB/SupportPackages/R20XXx/
Linux = /home/<username>/Documents/MATLAB/SupportPackages/R20XXx/
NOTE: ProgramData is a hidden folder, but you can use the shortcut %ProgramData% from Windows Search to jump right to the current user's ProgramData folder.

3. Open the 'Downloads' folder on your computer, then navigate to \MathWorks\SupportPackages\R20XXx\. Delete the contents of the "R20XXx" folder.

4. Run the Support Package installer again and re-install your Support Package now.

For R2016a and prior

1. Open MATLAB and choose the drop-down menu for "Add-Ons", followed by the "Get Hardware Support Packages" option. In the Support Package Installer choose the "Uninstall" radio button, then click "Next". Follow the remaining menus to uninstall the desired Support Package.

2. Navigate to the following folder on your computer and delete the contents you find there:

Windows = C:\MATLAB\SupportPackage\R20XXx\
Mac = /Users/<username>/Documents/MATLAB/SupportPackages/R20XXx/
Linux = /home/<username>/Documents/MATLAB/SupportPackages/R20XXx/

3. Open the 'Downloads' folder on your computer, then navigate to \MathWorks\SupportPackages\R20XXx\. Delete the contents of the "R20XXx" folder.

4. Open MATLAB again and run the following commands:

>>restoredefaultpath
>>savepath

5. Run the Support Package installer again and re-install your Support Package now.

NOTE:

This will remove all support packages that you currently have installed.

I had this problem with 2020 version and the problem was solved only by running the commands of step 4 and after restarting the program.

This helped me install it properly. But I lost previously installed tools. Is there any other specific things we ca do to avoid the same in future?

How do i selectively clean re-install selected support package? If i have 20 of them installed i can't afford removing them all just because one of them starts causing troubles.

Can you please provide details on how to do a clean re-install of a unique support package without deleting the other installed?

[Colin Fraser]

You would have to delete the specific folder related to the support package. This can be tricky as some support packages have multiple folders. I would contact us so you could troubleshoot this issue live.

For MathWorks, I confirmed the successfully installation of the Adalm-Pluto Hardware support package for MatLab R2021a. I recommend using the "install option" instead of "download only". For some reason (Firewall or whatever), I got stuck in downloading 3rd party vendor support files.
