If 'ctypes.windll.LoadLibrary' just calls the Windows API LoadLibrary function 
without adding any path, then the directories considered will only be those 
known to the Windows API, like e.g. the process' current directory (I'm not sure 
if the current directory is considered, but the details aren't important).

And most likely your calling script file is not in any of those directories.

Probably it will work to specify the full path to the DLL. You can obtain the 
path to the calling file's directory by using the __file__ variable and the 
'os.path' functions.

Cheers & hth.,
