Errors when trying to launch MATLAB through PHP

What's being attempted: PHP, running under IIS, is calling an executable that runs a MATLAB program

Where it's breaking: In the executable (written in C++), the engOpen(NULL) command is not launching the MATLAB engine successfully

Confusion: When logging in as a normal user and manually running the executable, the MATLAB engine launches fine and the program runs successfully. However, when IIS tries to run it the executable fails halfway through, at the point where engOpen is called.

Relevant Code:

#include "engine.h"
Engine *ep = NULL;
if (!(ep = engOpen(NULL))) {
  log_out << "Error opening engine." << endl;
  log_out.close();
    exit(-1);
}

Any help would be appreciated. We're currently unsure if the program is a MATLAB issue or a PHP/IIS issue, and could really use some pointers in the right direction.
