What's the difference between Matlab runtime and Matlab(R) Compiler Runtime

My comupter installed both Matlab runtime and Matlab(R) Comiler Runtime. See following picture. What's the difference between those two softwares?

The purpose for those two softwares is to do some calculation in excel file, but some function need support from Matlab.

The 7.14 software is for applications compiled with r2010b

Thanks for your answer at first.

The VBA program in excel file need to call some Matlab function. But why do I need two matlab programs? what's the real difference between two matlab programs?

[Walter Roberson]

MATLAB Compiled executables and generated libraries need a run time library that is specific to the MATLAB version they were compiled with. It is not possible to use the run time library for 2015b to run a program compiled with r2010b.

The two files you see serve the same purpose for different matlab versions. They changed the naming convention at some point from internal version numbers to matlab release names but they are the same purpose for different releases. Also it would not surprise me if the 7.14 one is for 32 bit r2010b programs; the other one is for 64 bit R2015b

Hello Walter,

Thanks for your support. I am trying to run a matlab compiled program and it shows as follow

"Could not find version 7.14 of the MCR. Attempting to load mclmcrrt7_14.dll". Please install the correct version of the MCR. Contact your vendor if you do not have an installer for the MCR."

How can I get a MCR 7.14? I am using MatLab 2021a.

[Walter Roberson]

MCR 7.14 is old enough that there were different license terms back then.

There are two ways to get MCR 7.14:

• the person who provided the executable is reponsible for providing that version of MCR to go with it. However, they had to restrict access to it: they were not permitted to make it open to public downloading. They could set up a password protected site or they could email it to you or whatever works out... just not public access. (My understanding is that this had to do with the license terms for software components that Mathworks was purchasing from some other organization.)
• Or: if you have a license for MATLAB Compiler for any release from R2010b onwards, then you are authorized to install R2010b and then use the development MCR from that.

Unfortunately, using a later MCR is not backwards compatible at all: it has to be specific to R2010b.
