I've exhausted the self-help resources. I downloaded all the 2020 versions (LabVIEW, RT Module, FPGA Module, and drivers) and I installed them in the order I just listed them in, which is the order described by the "Getting Started" online documentation.
I've connected from MAX to a cRIO 9024 my local rep loaned me, and uninstalled the software that was on the cRIO (the resident software was from 2015). I reformatted the "disk" (but preserved the static IP). When I go to install LabVIEW RT onto cRIO, I get an astonishing set of "unresolved dependencies", some of them referring to really old software versions. I've tried rebooting the cRIO.
Attached is the tech support report I ran in MAX, and here's 3 sequential MAX screenshots of my experience. I'm baffled. Thanks!
