4.11.2 Vr preview greyed out
Hello, I am new to the unreal engine but not to VR and the oculus series. I am unsuccessfully trying to run a DK2 runtime 1.3 with unreal 4.11.2 on a windows 7 machine. Whatever I do, I get the "VR preview" option greyed out which is insane because I though 4.11 was all about VR dev. Sooooo if anyone has a solution?
Things I've tried Uninst and reinst Oculus runtime 0.7, 0.8, 1.3 Shut down & restart Oculus runtime Update GPU drivers

You have to start the oculus desktop app first and turn the rift DK2 on. Than start UE4 v4.10.4 as a test. If this works try on 4.11. I got same problems with the 4.11 version. 4.10.4 works fine.

I've tried this and it doesn't work for me. It works on 4.10.4 but it's greyed out in 4.11.2

I had the same issue. This was a Unicode problem in my case. When UE4 installed on Windows it can work only with English characters. It is ancient bug.
So, what I've done to make it work: 1. Uninstall Engine, SteamVR and Steam or all Oculus software and clean registry 2. In Windows 10 go to Settings -> Time & Language -> Region & Language -> Set English language as default (install it if needed) -> click on "Additional date, time, & region settings" -> Region -> Administrative -> Copy Settings -> choose both check boxes and click Ok 3. In Region -> Administrative -> Change system locale -> choose English(United States) 4. If your current Windows user's name (account name) not in English language (my name was typed with Cirillic Alphabet) you should create new user in English 5. Relogin under new user then install all stuff again
This should work on Windows 7 too. Just keep in mind the main reason: characters Unicode problem
Maybe I made some extra steps to solve it. Maybe you don't need to change language for whole Windows, maybe it is enough to change "Current language for non-Unicode programs" option and set up new User in English, but i never checked it, because I feel comfortable with this settings
