I would just run a repair which should reinstall the current (v19) software. It works great with my Rift cv1 (also win10pro).
If you have been mucking around trying to get older versions to run then follow Oculus Support tips on how to fully uninstall your current installation. In that case you may be best to unplug everything, download the software, and go through the setup again.
Of course you could also reach out to Oculus Support. Even though the Rift cv1 is discontinued they still seem willing to help sort out issues. Good luck mate.
folks never read posts, they just come in with their own agendas. Tom would have seen that you did the re-installs. Anyways one way to get your system working for sure is to take another drive and upgrade/install WINDOWS 7 ULTIMATE (can handle 192GB ram) and follow the solutions on my post where you search reddit.
