Dear all, I had the same problem and I followed these suggestions. However, it didn't start working and I kept receiving my error message: "Unable to load DataSourceDll.dll. Please install Microsoft Windows SDK 7.1..."
Accidentially, i found another discussion on that topic (<http://www.mathworks.com/matlabcentral/answers/28894-problem-trying-to-load-dll-library-using-loadlibrary-error-is-a-selected-compiler-was-not-fou)>. And in fact,
solved the problem for me. Still don't know why. Just in case you have the same problem as me.
