This error will occur when trying to install products into an existing installation folder that contains a different Update level. 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. This will install all products to the same Update level.

If the online installation workflow cannot be used you will need to uninstall the installation of MATLAB, and reinstall. After reinstalling MATLAB, then apply the Update with either the online or offline workflow.
