Is the DLL loadable from a standalone C program?
All that is needed is a call to LoadLibrary() and check the return.
If the full path is not specified, the dll is searched in the predefined order
- I believe it is
executable directory - in this case, directory of python.exe
current directory - set the current drive and path to whereever you want
before trying to load the dll
windows system directory
windows directory
Directories specified in PATH evnvironment variable
