I received a vi from a contractor who told me I would need FPGA and Real-Time modules. I installed evaluation versions of those, then tried to load the vi. It could not find "nirviIntfOpen_cRio-9104.vi" and one or two similarly named files. I assume these are files that would be included with the Real-Time install. Why can't they be found? When I check the NI directory, I find many files with names like nirvi*.vi, but not this one.
