Dependency Walker

Dependency Walker is a 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. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.

Dependency Walker is also very useful for troubleshooting system errors related to loading and executing modules. Dependency Walker detects many common application problems such as missing modules, invalid modules, import/export mismatches, circular dependency errors, mismatched machine types of modules, and module initialization failures.

Dependency Walker runs on Windows 95, 98, Me, NT, 2000, XP, 2003, and Vista. It can process any 32-bit or 64-bit Windows module, including ones designed for Windows CE. It can be run as graphical application or as a console application. Dependency Walker handles all types of module dependencies, including implicit, explicit (dynamic / runtime), forwarded, delay-loaded, and injected. A detailed help is included.

Dependency Walker is completely free to use. However, you may not profit from the distribution of it, nor may you bundle it with another product.

What is New in Version 2.2:

• Moved to new HTML help system and updated the help text.
• Added support for MSDN 8.0 external help and updated the online help URL.
• Improved Side-by-Side support that handles DLL manifests and app.exe.local files.
• Updated internal information about known OS versions, build numbers, and flags up to the Vista RC1 build.

Dependency Walker is part of several Microsoft products, such as Visual Studio, Visual C++, Visual Basic, Windows 2000/XP/2003 support tools (on the Windows CD), Windows 98/NT/2000/XP/2003 Resource Kits, Platform SDK, Windows DDK, Windows SDK, and MSDN.
