I just picked up a rift today and installed the software and get this error. I can't even use my rift on day 1. I saw there was a patch from a couple weeks ago, that didn't help. I've uninstalled, restarted and fresh installed a few times now. Still same error, ugh. Any support guys around here to help?
I received the same error today but found that the OVRService was stopped in task manager. I started it and was able to open Oculus just fine after that. I then ran into an issue with Malwarebytes preventing an update, so I exited out of that. Both of this combined led me to using my oculus without a problem.
(Note I had disabled the OVRService previously so this may not be relevant at all.)
