Hi @舜彬 张

It seems like you're looking to reactivate MATLAB after an incorrect initial activation and are facing an error during reinstallation. You can follow these steps to resolve this:

• Uninstall MATLAB: Follow the uninstallation to remove MATLAB completely.
• Clear Temp Files: Delete MATLAB-related temporary files from the `%TEMP%` folder.
• Download Installer Again: Get a fresh copy of the MATLAB installer from your MathWorks account.
• Run Installer as Admin: Execute the installer with administrative privileges.

Refer to the following MathWorks Documentation for detail about uninstallation and activation
