Eric, Try adding this to your LabVIEW settings file. I'm not certain that it will fix your problem, but it might.
BldApp.RemovePolyVIsandTypedefs=False ###################### By default, LV7 AppBuilder does not include type definitions and unused instances of polymorphic VIs into executable in order to decrease size of application. If some VI in your exe calls a VI outside (that was not planned by AppBuilder) and uses a type definition in order to pass parameters, you will meet such kind of problem for sure. This undocumented ini setting disables this new feature. ###################### -Jim Eric Samsel wrote: > I'm trying to use the Call by Reference node to dynamically call certain > subvi's.
