Ok, so I've learned that in order to run this interop, I need NationalInstruments.LabVIEW.Interop.dll. Unfortunately, LabVIEW RunTime on this machine inexplicably does not have NationalInstruments.LabVIEW.Interop.dll with it. I am toying with trying to download the dll from one of those sketchy dll sites, but this may be not recommended. Is there another way for me to get this dll?
Thanks Dennis for all your help. Hopefully someone else may be able to chime in.
