Oculus has released instructions for downloading the software update that fixes the error and gets players back into their VR games. The head of Rift also says store credit will be offered to those affected.
Quick update: We're still actively working on an issue with our software certification. We're looking at a few different ways to resolve the issue and will share updates. We recommend you wait until we provide an official fix. Thanks for your patience. https://t.co/JMqQ4nvVKY— Oculus Developers (@Oculus_Dev) March 7, 2018
If you've attempted to boot up some VR goodness today on your Oculus Rift, you've probably encountered the "Can't Reach Oculus Runtime Service" error. There's no official fix right now, but Oculus is aware and working on it right now.
As shown in the Oculus forums, it looks like the cause of this particular error is an expired certificate. One user suggests that a temporary band-aid is to set your system clock back two days, but we can't confirm if this works or not. Also, this solution may interfere with other installations on Windows 10, so we don't recommend it.
We're aware of an issue affecting Rift on PC, and we're working on resolving now. Stay tuned.— Nate Mitchell (@natemitchell) March 7, 2018
All that's left to do for now is playing the waiting game and dive into some non-VR games in the meantime. You could also peruse over our Most Anticipated VR Games of 2018 list. We'll update this story as more information is made available.
