Matlab NE Builder "Access Violation"

I'm using deploytool to create a Matlab class (MLTestClass) with a method (makeSqr) as shown in the MathWorks tutorial linked below. After importing the relevant libraries in Visual Studio 2012, the line `MLTestClass obj = new MLTestClass();` causes the program to crash with an "Access Violation." I'm using MCR v8.1. I've seen somewhere that this can be caused by compiling the .m file with the wrong compiler, but the only compiler I have on my computer (according to `mbuild -setup`) is "Microsoft Visual C++ 2012" (although I'm compiling for use in a C# project, if that makes a difference).

Thanks for any help!

I think that it may be a problem where I'm using a 64-bit version of Matlab 2013a, and Visual Studio is only 32-bit. Is there any way to get around this?
