Error "IVI Driver Session Has Invalid Software Module"

[OregonGumby]

I am upgrading a test system to a new PC with Windows 10 and LabVIEW 2016 from Windows XP and LabVIEW 8.5.  When I run this NI Switch executive VI on the new system, I get an error.  It runs fine on the old one.  I also tried doing a Validate in NI Max for the virtual channel and it gives the same error.  I did imports from the old system for all the IVI drivers and virtual devices so they look identical on NI Max.  Not sure why it's not working.

Please check the prefix(case sensitive) for the specific switch which causes these errors.
