dcontinpals.dll file issue

[Collins-Ogbodo]

I have been experiencing this error in these lines of the code, could you tell how to get around it, please?
file_name = 'dcontinpals.dll'
__dllPtr = cdll.LoadLibrary(file_name)

Could not find module 'dcontinpals.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I have also tried to use os to get full path but it didn't work

I have experienced the same problem, even with simpler code, just to load any other .dll. This documentation on ctypes does not show the same error with loading dynamic link libraries
(LoadLibrary()), but there is a way to debug what is going on:

" To resolve this error and determine which DLL is not found, you need to find the list of dependent DLLs and determine which one is not found using Windows debugging and tracing tools."

Following up on this a bit late. The specific dependency missing was (for me) "libquadmath-0.dll." Adding that dependency to the directory DCONTINPALS/pyDCONTINPALS fixed the error in Python 3.7. I believe newer Python versions changed how libraries are loaded, so a FileNotFound error will still occur in Python 3.13, for example, but that is a separate issue.
