title: Retrieving COM class factory error: 8007007e after hosting in IIS
body: <p>I have a Web API application which uses a managed dll as a reference.This managed dll referes to COM+ dll using Interops.So this Web API application works fine on localhost, but after deploying it into IIS server I am facing the exception</p>
  
  <blockquote>
    <p>"Retrieving the COM class factory for component with CLSID
    {90865CE9-F9F4-11D3-8FD8-080036DF2204} failed due to the following
    error: 8007007e The specified module could not be found. (Exception
    from HRESULT: 0x8007007E).":null</p>
  </blockquote>
  
  <p>This clsid is unmanaged dll. I checked the registry and this clsid has been registered in both 32 bit and 64 bit.While deploying in IIS, I even kept enable 32-bit Applications to <strong>true</strong>.But still I am facing the same exception.
  So is there any trick I am missing here?</p>
