For example, on Windows, close MATLAB and re-open it using right-click "Run as Administrator" before attempting to install the support package again.
2) Connection errors
If you experience a connection error in the Add-Ons Explorer, you can use the offline installation workflow as a workaround. The Support Software Downloader can be used to obtain offline installation files for the Support Package.
