Have you tried examining the DLL with DependencyWalker ?
Also sometimes details about failed DLL imports can appear in the
Were you building previously against Python 2.3 and 2.4 using MSVC 8 ?
If not you may now be encountering a a c-runtime conflict although
that's just a guess. If that is the problem, try building a Python 2.5
from source with VC 8. This will make your build non-standard though, so
then you face issues distributing your DLL.
Good luck,
