These are generic error messages typically caused by a permissions issue, a connection error, or a corrupted installation.
1) Permissions related errors
In order for most support packages to complete installation, the Support Package Installer requires sufficient permissions. If installing the Arduino Support Package with the Add-On Explorer, restart MATLAB with elevated privileges. 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. If you experience a connection error with the Support Software Downloader as well, try running it on a different computer and then transfer the files over. For more information, see this article:

Note: For Windows Machines, verify that BitLocker is not enabled before attempting to boot in Safe Mode.
3) Corrupted installation
You may perform a clean installation of the support packages to remove any potential corruptions. To do this, follow these steps:
