The installer times out on "Working...". I killed the setup the first time this happened after about 2 hours of waiting, and when I restarted it it popped up with "Already Installed", but launching it causes an error saying "Can't reach oculus runtime service". Both the "repair" and "uninstall" options get stuck in the "Working..." screen without any output. Task manager shows the CPU and Memory usage changing, so I don't think it's stuck in an infinite loop or something. What should I do?
