MCRInstaller supports the installation of
multiple versions of the MATLAB® Runtime on a target machine. This
allows applications compiled with different versions of the MATLAB Runtime to
execute side by side on the same machine.
If you do not want multiple MATLAB Runtime versions on the target machine, you can remove the unwanted ones. On Windows®, run Add or Remove Programs from the Control Panel to remove any of the previous versions. On UNIX®, you manually delete the unwanted MATLAB Runtime. You can remove unwanted versions before or after installation of a more recent version of the MATLAB Runtime, as versions can be installed or removed in any order.
