#error WINDOWS.H already included. MFC apps must not #include <windows.h>

c++, mfc, windows

Solution

Try turning on "Show Includes" in the projects settings (C/C++ -> Advanced). This show give you an indication of what header files are included and in what order - you should be able to trace back from there

Problem
