Hello j4nnet,

Make sure that "SDK\Bin\Win32_x86/Win64_x64\FScanners\NdmDigitalPersonaUareU" is present in your project's working directory.

Send small test application with an issue description to support@neurotechnology.com.
Also please provide SDK revision number(can be found in SDK root directory, in Revision.txt file).

I had the same problem. Seems like there is a problem when reading both Neurotechnology Devices DigitalPersona U.are.U and Neurotechnology Devices DigitalPersona U.are.U One Touch modules for the 4500 device DLL.
I found that the scanner works fine when ONLY using the DigitalPersona U.are.U One Touch Module.

Try removing the DigitalPersonaUareU folder under location ..inwin64_x64FScanners if your system is a 64-bit system or ..inwin32_x86FScanners if it is 32-bit system.

Hope that helps.

Cheers!
