I’ve seen other threads about this issue, but not really a clear solution for it. I have a fresh install of Driver4VR 4.4.0.0 beta and SteamVR is not in beta. When I try to launch SteamVR it seems that Driver4VR loads first and shows the error ‘Unable to connect to SteamVR Error: IPC_Connect Failed’. Then SteamVR shows Not Ready and gives the ‘key component of SteamVR is not working error 301’ message.
I saw someone saying that they fixed this error by getting steamVR working and then starting Driver4VR after, but I’m not sure how to get Driver4VR to not launch at the same time. I’ve also restarted both programs and my computer a few times, and reinstalled the tool.
