Hello, GonzaloMoline.
It may be incorrectly installed scanner drivers. What message, RC and CC code contained in the exception?

Hello, the driver was correctly installed, but, when you have two drivers installed (ds30 and ds40) you have to configure de default driver and this was the error. The program tried to use de scanner ds40 with the driver ds30.
When I did this configuration the problem was solved.
Thans a lot for you answer.
