It is often referred to as the Primary Interop Assembly (PIA). COM Wrapper: It wraps the Inventor.exe COM type library.
When an Inventor version is installed, its specific Autodesk.Inventor.Interop.dll is added to the GAC. This results in a single folder ( C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Autodesk.Inventor.Interop ) containing numerous versioned subfolders (e.g., v4.0_17.0.0.0... , v4.0_26.0.0.0... ). This allows multiple versions to coexist without conflict.
Your application architecture does not match the Inventor installation architecture. (e.g., Running a 32-bit x86 application against a 64-bit x64 Inventor installation). Core Concepts & Examples : C:\Windows\Microsoft
