When I did the 1.3.0 install for my DK2 there were various parts of the consumer software installer/setup routine that complained at me, but that might have been something to do with the particular usb ports on my motherboard and despite the errors and stages I had to skip, everything seems to be working really well with 1.3.0 in general once I got to the end of the process. I look forward to trying it with UE4 but I’m only just returning to trying UE4 again now and find myself needing a new hard drive to make room on my dev pc.
Also note that you might need to update your graphics card drivers to maintain Oculus compatibility, I added that info to my original post but I think you’d already read it and replied by then.
