Yes, but why? The Firebird bin directory is in the path (and it's the first entry there), _and_ the dll is in \windows\system32. Instclient.exe puts it there with the name all uppercase ("FBCLIENT.DLL"), but that shouldn't matter with Windows, should it?

 may be a bug in ctypes.util.find_library

cf (http://grokbase.com/t/python/python-bugs-list/12akm2rs91/issue16283-ctypes-util-find-library-does-not-find-all-dlls-anymore)

 

so try :

from ctypes import *
from ctypes.util import find_library
 
fb_library_name = find_library('fbclient.dll')
