In order to use an ActiveX component in a .NET programming laguage, it creates wrappers that will call the ActiveX DLLs.
The solution is to add the “AxInterop” and “Interop” files with your setup. The AxInterop file is only generated when you add the component on the form. However, if you are simply using the component as a reference, then only the Interop is generated.
