Hi NVU,
Thank you for your answer. I tried that. First it offers me to uninstall the application builder and no more. When I tried that again then i received a message: �NI shared components were detected that are not associated with any products. Would you like to remove these shared component?� and no option to uninstall the LabView 7.1. I am using Windows NT, may be that is a problem.
Thanks,
Andres
