I started with Anaconda3 (python3.64). When I add #include "python.h" to my C++ code, I get the visual studio 2012 compile error:
anaconda3\include\pyport.h(6): fatal error C1083: Cannot open include file: 'inttypes.h': No such file or directory

I then installed python 3.7, and put that include directory into my project. But I get the same error when I try to compile. 
python.h calls pyport.h, which tries to call inttypes.h, which it can't find. I searched and cannot find inttypes.h anywhere on my computer.
