Hello. I am having the same problem. Read all the comments, but Ralf is repeating himself like a broken record without reading people’s comments. No offence, but people have been saying that the latest runtime only works with the newest Oculus technology. It doesn’t work on DK2 anymore, I’ve tried it. And when you try to launch vorpX with beta version, it gives this exact error here. Please, fix this. Not all people have the newest oculus, there are with DK2 as well.
