This is a list of the library versions used by Autodesk Inventor; these are located in Inventor’s Program Files bin directory. A sometimes frustrating part of developing software that integrates with Autodesk Inventor is chasing down bugs that are caused by assembly mismatches. If your addin uses a different library version that Inventor has in memory, and you happen to hit an incompatible call, you’ll often get some unknown exceptions.
