Hi Berenice,
Thanks for using our discussion forums! Unfortunately, Vision 5.0 for CVI is not meant to support LabVIEW 6.1. If you want to use Vision with LabVIEW, give us a call and we can discuss the possibilities- we are currently up to version 7.1.1 of our Vision Development Modules for CVI and LabVIEW.
