I think you are executing your application on 64-bit system which have 32-bit TWAIN driver for your scanner but does not have 64-bit TWAIN driver. Please compile your application in x86 mode and you will be able to see TWAIN driver of your scanner in a list of scanners.

Also please read the "I cannot see devices in the TWAIN selection dialog of my application but can see them in other applications. Why?" topic here: ... oting.html

Best regards, Alexander
