SequenceView control doesn't display in deployed UI

Hi, Teststand users.  I placed a Teststand SequenceView control on my custom Labview UI, and it updates correctly on my development station as the sequence executes, including after I've built the UI into an EXE.  But when I deploy the package to a test station on the manufacturing floor, the SequenceView stays blank throughout the sequence, which executes correctly to completion.  The test station has Labview Run-Time Engine 2015 installed and Teststand sequence editor 2014 SP1.  Any idea what could cause the SequenceView to not update?  I'm calling the ExecutionViewMgr > ConnectExecutionView function in the normal recommended way.

Thanks.   -Joe Czapski
