Here's the answer. First, GdPicture 9 works with Windows 10. But the machine in question had been upgraded from some prior version of Windows. This resulted in c:\windows\system32\TwainDSM.DLL landing in some strange state, where it could not be seen in the folder, nor could it be listed with a Dir ...

The problem may be that the GdPicture is simply not finding the driver. Where does Select Scanner store the scanner selection setting?

Are there any known issues using GDPicture 9.1.0.3 with Windows 10 scanner drivers? We are have trouble with our entire application crashing when attempting to scan or acquire via TWAIN after an upgrade to Windows 10.

I don't see where GdViewer is given a reference to GdPictureImaging. >To release a particulat image to the stack, just use the ReleaseGdPictureImage method. Would you ever...

As a potential customer, I am currently evaluating your TWAIN/Imaging product, in particular, your TWAIN C# sample code, in an attempt to see how it all works and how the underlying architecture holds together.
