CANopen Functions Palette is missing in LabVIEW

Issue Details

• I have installed the NI-Industrial Communications for CANopen, but the CANopen Functions do not appear in the LabVIEW block diagram function palette.
• I don't have the CANopen functions; my palettes are empty. How can I access the CANopen functions?
• When I open a VI, it complains that I am missing VIs from CANopen.  Additionally, those functions in the VI show up as question marks on the block diagram.
