Dependency Walker

Why Use Dependency Walker? The following is a list of reasons why you may find it useful and a link to the download site.

Have you ever...

• wondered why an application or module was failing to load?
• wondered what minimum set of files are required to run a particular application or load a particular DLL?
• wondered why a certain module was being loaded with a particular application?
• wanted to know what functions are exposed by a particular module, and which ones are actually being called by other modules?
• wanted to know the parameter and return types of exported C++ functions?
• wanted to remove all dependencies for a given module?
• wanted to know the complete path of all the modules being loaded for a particular application?
• wanted to know all the base addresses of each module being loaded for a particular application? What about versions? Or maybe CPU types?

Have you received one of the following errors...

• The dynamic link library BAR.DLL could not be found in the specified path...
• The procedure entry point FOO could not be located in the dynamic link library BAR.DLL.
• The application or DLL BAR.DLL is not a valid Windows image.
• The application failed to initialize properly.
• Initialization of the dynamic link library BAR.DLL failed. The process is terminating abnormally.
• The image file BAR.EXE is valid, but is for a machine type other than the current machine.
• Program too big to fit in memory.
