I think I'm getting the same error as the other person (c.barca) with GdPicture, but on the GdViewer Pro. I'm running VB.NET 2005 and the latest sample available on your website.
Reference required to assembly 'GdViewerPro3', Version=1.3.0.0
The project currently reference AxInterop.GdViewerPro3.dll version 1.2 and Interop.GdViewerPro3.dll 1.2
In removing these and registering the newer 1.3 component, it will say:
Type 'AxGdViewerPro3.AxGdViewer' is not defined.
