Application  environments can become complex with multiple software applications  sharing the same system resources and DLLs. Occasionally, a DLL may be  replaced or registered by the operating system that is incompatible with  a particular version of an application. Dependency Walker is a useful  utility that allows you to find the DLLs used by an application and  possibly identify the source of a problem. You can use the How to generate Dependency Walker log files for Customer Support doc, including a video demonstration, to identify these problems on  your own or speed up the resolution by provided a Dependency Walker log  file to Customer Support.
