Why do I receive an error message of "mclmcr.dll not found" while deploying my application on a target machine using the 'MCRInstaller.exe' in MATLAB 7.0.4 (R14SP2)?

Hence, the other option is to reinstall the MCR using 'MCRInstaller' on the target machine.
You can find the 'MCRInstaller.exe' in the following directory:
(where $MATLAB is the MATLAB root directory as returned by the following command:
