In order to use Vision with LabVIEW 7.1 you will need the Vision Development Module 7.0. The upgrade to Vision Builder 6.1 is Vision Assistant 7.0. Vision Assistant 7.0 is included with NI Vision Development Module 7.0. Your Internal Sales Representative or your Field Sales Engineer should be able to assist you in upgrading.
