BizTalk Pipeline Component – The specified module could not be found. (Exception from HRESULT: 0x8007007E) error.

Recently I tried to install an old BizTalk pipeline component project into a new environment, but it failed, giving the following error:

“The specified module could not be found. (Exception from HRESULT: 0x8007007E)”


  • Your DLL (component) depend on other DLL’s to get its job done and if you didn’t copy or install those too, you’d indeed get this error message.

Because this was an old project, the difficulty was to know all the dependencies.


  • You need to figure out what dependencies are referenced (directly or indirectly) by the component, so try to use one of these tools:
    • DependencyWalker, FileMon or ProcessMonito. And find out what the dependencies that are missing.
  • Copy the missing dependencies to the folder “C:\Program Files\Microsoft BizTalk Server 2006\Pipeline Components” or install them in GAC
