Best Answer

This error will occur when trying to install non-updated products into an existing installation folder that contains an update. The resolution is to install online using the MATLAB Installer by selecting the "Log in with a MathWorks Account" option to download your remaining product installation files.
If you need to use the offline workflow, you will need to uninstall MATLAB and all of its toolboxes and reinstall. After reinstallation, you can then apply the offline update installer.
