Dependency Walker

Dependency Walker is a useful, free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. It runs on Windows 95, 98, Me, NT, 2000, XP, 2003, Vista, and 7.

It’s useful to determine what’s missing when you’re loading a DLL.
