I am running an executable matlab program that is using a mexw64 function, which is linked to a .dll. It runs fine on my computer, and on some other machines (so i know its not a lnk error), but not on machines w/out a c/c++ compiler. Is there any way to use this mex function w/out a c compiler? or somehow combine the .dll with the mex into one mex function?

If no for both of these, does anyone have any idea how i can throw this mex in a try catch, and if it goes to catch(no c/c++ compiler installed), make it automatically download a free .net c++ compiler?

Typically you don't need the C compiler itself installed, you only need the libraries, which are usually free to download and install.

I agree with James. However, I wonder if you are compiling with Visual Studio. If so, you probably need to have the Visual Studio Redistributable Package (and not the compiler itself) available at runtime. You can't throw across the MEX interface to MATLAB, but I think you can have a try-catch block inside the MEX-function and return an error to MATLAB using mexErrMsgTxt.
