MATLAB Compiler Runtime requires the correct version installed to run a compiled application.
The version information is recorded in the VersionInfo.xml file in the MATLAB Runtime installation folder. For example, C:\Program Files\MATLAB\MATLAB Runtime\v910\VersionInfo.xml.
If you want to check it programmatically, the MCRVERSION function can help you determine the MCR version of a copy of MATLAB, while the VER function can help determine the version of the MATLAB Compiler toolbox. Starting from R2020b, you can also use matlabRelease function. For more information on these functions, execute the following lines of code at the MATLAB command prompt:
help mcrversionhelp ver\nhelp matlabRelease
