Can I Use LabVIEW Express VIs as User-Defined Steps in SignalExpress?

Primary Software: LabVIEW Signal Express>>Development System
Primary Software Version: 1.1.1
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem: When I try to add a User-Defined Step and select an Express VI that was installed with LabVIEW, I get an error that says "Failure Opening VI". Can I use LabVIEW Express VIs as User-Defined Steps in SignalExpress?

Solution: Express VIs intended for use in LabVIEW cannot be directly used as User-Defined Steps in SignalExpress. However, LabVIEW Express VIs may be used in SignalExpress if they are first placed in a wrapper VI, which will be called as the User-Defined Step. In this situation, the wrapper VI is a LabVIEW VI that includes an Express VI on its block diagram with the inputs and outputs of the Express VI wired to controls and indicators on the wrapper VI's front panel. You will then need to follow the steps outlined in KnowledgeBase 3LAGC9L2: VI Guidelines for User Defined Steps In SignalExpress to enable the wrapper VI to be used as a User-Defined Step in SignalExpress.
