I am trying to open a 32 bit dll library and need to use 32 bit MATLAB to do so. If there is a way to do this in a later version of MATLAB running 64 bit, I'm currently unaware. I am trying to get a C++ compiler setup with MATLAB 2015b (32 bit version), but I'm unable to do so. I have tried installing TDM-gcc version 4.9.2 (the supported compiler according to https://www.mathworks.com/matlabcentral/fileexchange/52848-matlab-support-for-mingw-w64-c-c-compiler) in folder C:\TDM-GCC-32. I have tried:

setenv('MW_MINGW32_LOC','C:\TDM-GCC-32')

mex -setup C++

but I get an Error saying "no supporting complier or SDK was found."

I have also tried downloading the MinGW compiler and using that instead. Where I set the environment to look at that folder instead and have gotten the same error message.

The original dll file was compiled in C++, wouldn't I need C++ libraries to decompile the dll file?

I don't know about decompiling, but you shouldn't need them to run the function, at least as far as I'm aware.

I had the same problem and this workaround resolved the issue:

https://social.msdn.microsoft.com/Forums/sqlserver/en-US/1de7c9b4-1feb-4c98-b426-f7f02cbafa99/windows-sdk-71-on-windows-10?forum=windowssdk

1. Uninstall any Visual C++ 2010 Redistributables from the control panel first.

2. Download the corresponding offline ISO image from the Windows SDK archive.

3. After mounting the image, open F:\Setup\SDKSetup.exe directly.
