MatLab App versus MatLab Compiler Runtime version requirements

Greetings,

Can someone please advise if MatLab 2023b requires MatLab Runtime 2023b or will MatLab Runtime 2023a work? We have MatLab 2023b and Compiler Runtime 2023a, will this work together?

If MatLab and Runtime require specific versions is there an Archive or somewhere either Runtime 2023b or MatLab 2023a can be downloaded?

Appreciate the clarification and assistance.

My experience has been the installer will find and download the needed runtime if it isn't already on the system.

Also by observation the installer does require the runtime consistent with the version that compiled the app. One can/does end up with several versions on a target machine.

So far, I've not had to do a separate manual download/install of the runtime on a user's machine; by using the packager, it seems to handle that on its own ok. I do not know of anywhere it is specifically addressed in the documentation, though.

If/when MatLab App is installed, there is no option to include or install the Compiler Runtime. Instead the Runtime can be downloaded from MatLab Runtime at the link below. Also according to MathWorks Support, the version of the App and Runtime are version specific, which means App R2023b will NOT work with Runtime R2023a.

How are you building the app? I've used the packager interface inside App Designer and its behavior has always been as noted above. However, I guess I should note that I've not yet gone past R2022b so I suppose the behavior could be different on later releases. I've also only built and distributed compiled executables so that might make difference on other types; I didn't think of those earlier.

I only perform the install and sys admin tasks and leave the app building and compiling to developers. According to my development team, which they have confirmed, the combination of MatLab App R2025a with MatLab Runtime R2023a works if the code does not need to be compiled or recompiled, instead the Runtime is used by the 3rd Party App to run the MatLab executables.

This saves us time with reinstallation and getting another license. Thanks for the assist with this.

Gotcha.
