Hi condor31,
DIAdem 10.2 is the first DIAdem version that is VISTA compatible. Even the DIAdem Base license will allow your users to edit and create REPORT and VIEW layouts, so I don't see any way to stop users from doing that. The Base license will not offer an easy way to create DataPlugins, though, so you could discourage users from writing DataPlugins by assigning them to the Base license list. The NI Volume License Manager utility enables you to specify who is allowed to check out what type of DIAdem license (Base, Advanced, Professional). That is really your only recourse-- DIAdem is otherwise an open tool that encourages users to take advantage of activated features.
Ask if you have additional questions,
