When using a Microsoft Lifecam on Windows 10 it may not show as an available video source.
The Microsoft website only lists a supported driver up to Windows 7 and although the bundled software appears to work ok on Windows 10, the driver does not seem to work correctly and does not show the camera as an available source for CardExchange.
Copy the VideoDS.DS file to your C:\windows\TWAIN_32 folder.
Restart PC.
You should now have a Twain Device Driver which should add the camera as an available TWAIN source that can be used by CardExchange:
