Are you sure you actually do have MATLAB installed?

You refer to a directory `C:\my_app\app\mcr\v717\bin`

. This directory is not typical of a MATLAB installation - instead, it's typical of where you might install an application that has been created with MATLAB Compiler.

In case you're not familiar with that, MATLAB Compiler is an add-on product for MATLAB, that allows you to create standalone applications from MATLAB code. These applications are distributed along with a MATLAB runtime (the MATLAB Compiler Runtime, or MCR, which is what you see in the directory path you have), and they run without you needing to have MATLAB installed.

Can you actually start MATLAB itself, either from the Windows command line with the command `matlab`

, or from an icon? If so then, as others have suggested, when MATLAB starts it should have its own command line. If you type `matlabroot`

into that command line it should give you the location of the MATLAB installation.

If you can't start MATLAB itself, then I would suggest that you don't actually have MATLAB itself installed, but perhaps instead have an application produced with MATLAB Compiler.

`matlabroot`

inside matlab I would think – Dan May 7 '13 at 8:06
