Don't know much about DLLs specifically, so let me ask a potentially dumb question. When does it try to load a DLL? Could it be that the difference seen is because one program tries to load libraries and the other doesn't get that far? I ask because, at least with the old C and Unix dynamic libraries, it would be quite easy to compile your program with no errors and yet have it fail to actually run.
Other things:Is there an easy way to tell where it's looking for libraries, and/or where it found them?In particular, could there be a 32- vs 64-bit problem?An example in wikipedia (in https://en.wikipedia.org/wiki/Dynamic-link_library#Python) suggests you can directly try to load a DLL:
import ctypes
my_dll = ctypes.cdll.LoadLibrary("Example.dll")
Looking at the Python docs, seems like ctypes.util.find_library(name) will return the path for the library. Also, perhaps ctypes.OleDL and ctypes.WinDLL will be useful. Maybe they have better error handling. (I think you'd use these instead of ctypes.cdll.)
