VB.NET and AutoDesk Inventor 11 Customization Problems

Question

I've done some looking through the site and on the Internet trying to find a solution to a problem with a VB.NET application I'm attempting to create. Unfortunately, I'm stumped by an error message that has prevented me from moving forward with any Inventor customizations.

Tools: Visual Studio 2005 sp1, Inventor 11 Stand Alone install
OS: Windows Vista 64 sp1

I installed the developer tools under the SDK folder. I then added a reference in my VB.NET project in COM to the component named: AutoDesk Inventor Object Library. It appears under references for my project as:

Reference Name: Autodesk Inventor Object Library
Type: COM
Version: 1.0.0.0
Copy Local: True
Path: C:\Users\rschmalt\Visual Studio 2005\Projects\
        InvTest\InvTest\obj\Debug\Interop.Inventor.dll

My code is as follows:

'Opens Inventor Apprentice session to read part numbers

Dim oApprentice As New Inventor.ApprenticeServerComponent
Dim asmDoc As Inventor.ApprenticeServerDocument
Dim refDoc As Inventor.ApprenticeServerDocument

asmDoc = oApprentice.Open(strIAMLocation)

For Each refDoc In asmDoc.ReferencedDocuments
  MessageBox.Show(refDoc.FullFileName.ToString)
Next

When I execute it, I get the following message:

Retrieving the COM class factory for component with CLSID {C343ED84-A129-11D3-B799-0060B0F159EF} failed due to the following error: 80040154

I have tried browsing directly to the DLL (Interop.Inventor.dll) and it then shows up as a .NET type in references, but the error remains the same.

Is it possible there is a conflict between vista 64 (Inventor 11 is 32bit)? Any suggestions?
