No Sources To Select From

I have just begun evaluating this SDK. I had some trouble with the Data Source Manager but I think that is resolved now, the device manager does Open() without error. Now my issue is that I have no devices to select from. Devices count is zero and if I call Select() there is nothing in the list.
The sample applications work, but the demo code does not. My scanner is definitely installed and working. Am I missing something to populate the devices list? It is my impression that the DSM handles that.
Thanks.

Hello,

I think you have x64 version of Windows and you are compiling your application in "Any CPU" mode. In this case you need to have x64 TWAIN drivers for scanners.

We recommend use "x86" mode because all scanners have x32 TWAIN drivers but only new and professional scanners have native x64 TWAIN drivers.
