Matlab Compiler is not linked to Matlab

Hello, I just installed Matlab and the Matlab Compiler for 2017a. I want to use the mcrinstaller because I have an executable which runs with mcr 7.13. If I type in mcrinstaller into matlab it says that there isn't a matlab compiler installed. I also added this C:\Program Files\MATLAB\MATLAB Runtime\v92\runtime\win64 to my path variable. Do I have to do something else to link matlab to the matlab compiler so that I can run the command the mcrinstaller?

Thanks for your help!

I have the same question, have you solved it yet?

I do not think that you installed the MATLAB Compiler product. I think you only installed one of the MATLAB Runtime libraries for use with programs compiled with the Compiler product

No I installed the Matlab Compiler from this Website https://de.mathworks.com/products/compiler/mcr.html

Please re-read the documentation there. I am automatically re-directed to the English version of the page, but I saw enough of the German version that I could tell it said much the same thing:

"MATLAB Runtime

Run compiled MATLAB applications or components without installing MATLAB

The MATLAB Runtime is a standalone set of shared libraries that enables the execution of compiled MATLAB applications or components on computers that do not have MATLAB installed."

This is not a compiler itself: it is a support library for things that are already compiled.

For example, every program compiled by MATLAB Compiler needs to know how to allocate memory for variables. Suppose that code required 20 megabytes. You could have the code for that in every compiled program; if you had 10 different compiled programs on your system, that would add up to 10*20 = 200 megabytes. It is the same code for each program, so a different way is to put the code into a library that can be called by all of the different compiled programs: then it would only take the 20 megabytes once no matter how many different compiled programs you had on your system.

Okay, then I missunderstood it. Neverless there is the question how to run an Application which is compiled with an older Matlab version. Is there a Matlab command?

[Walter Roberson]

You need to get MCR 7.13 (for R2011b) from whom-ever created the executable you are using. The licensing for MCR was different back then: it was permitted back then to make compiled executables available for anonymous download, but access to MCR had to be controlled. You will not be able to get MCR 7.13 alone from Mathworks.

(Note: if you have a MATLAB Compiler license for any later release, you could download an earlier release of MATLAB Compiler and get MCR that way.)

There is no way to use a more up-to-date release to run something compiled with an earlier release.

Check if you have MCRInstaller at this location- 'C:\Program Files\MATLAB\R2017a\toolbox\compiler\deploy\win64\MCRInstaller.exe'

If not, try to re-install MATLAB and MATLAB Compiler. If that does not resolve the issue, contact MathWorks Technical Support

[Steffen Koop]

Thanks for your answer! There is no path like this. In "C:\Program Files\MATLAB\MATLAB Runtime\v92\toolbox" there is a "compiler" folder but also no MCRInstaller.exe . I reinstalled both a few times and I also installed them on a different Laptop but there occures to be the same error...

The MCRInstaller is not started from inside Matlab. It is the idea of the Matlab runtime and compliled application to run independent from Matlab. So start the MCRInstaller from a shell of the operating system.

[Steffen Koop]

But shouldn't be there at least a MCRinstaller exe anywhere? I did not find such a Programm. Neither in the matlab compiler path nor in the matlab path
