Best Answer

The MATLAB Compiler Runtime (MCR) enables you to run applications compiled within MATLAB using MATLAB Compiler. MCR does not require a MATLAB license and can be used to run the MATLAB compiled program on computers which do not have MATLAB installed. 
For R2018a and newer, you can run the following command to install MATLAB Compiler Runtime. This command will only work if you have MATLAB Compiler installed and activated, have a working internet connection, and do not have a proxy or firewall.
>> compiler.runtime.download
(Note: Starting from R2019a, if you have updated your MATLAB software, the compiler.runtime.download function will download the MATLAB Runtime installer that corresponds to the update level of your MATLAB software.)
Or, to obtain an URL which you can then open in a web browser to download the correct version:
>> com.mathworks.toolbox.compiler.MatlabRuntimeUtils.getMCRInstallerDownloadURL()
Installers for the current versions of MATLAB Compiler Runtime can also be found on our website at:
These installers can be used offline, as the download contains all the files needed for a complete MATLAB Compiler Runtime installation. For releases before R2019a, runtime installers for General Releases will be downloaded. For releases starting from R2019a, runtime installers for the latest update level will be downloaded.
Running a MATLAB Runtime installer that is tied to a software update will remove any existing installation of the runtime for that release and install the MATLAB Runtime at the installer's update level. MATLAB Runtime installations from other releases will remain untouched.
It is possible to run applications with a MATLAB Runtime update level which is newer than the MATLAB release used to build the application. However, when creating "Runtime included in package" installers, the MATLAB Runtime version and update level needs to exactly match the MATLAB Compiler version and update level that was used to compile the application.
If you need to install an older version of MATLAB Compiler Runtime, please see the following article:
