Game Won't Launch with Mother VR Mod Installed - PLEASE HELP!!

[Sunlounger]

Hey guys,

The game launches fine without the Mother VR Mod installed, but as soon as i have the Mother VR .dll file copied into the game folder, the game will not launch when I press Play in Steam. I've tried downloading 3 different versions of the mod and none of them work for me.

Any help would be greatly appreciated as I finally got my Oculus Quest headset setup today with Oculus Link to my PC and bought Alien Isolation specially to play in VR with it.

Thanks guys for any help at all

I'm afraid I can't help with VR as I have no experience with it whatsoever. There are lots of people who play this in VR though so I'm sure you can find a guide, or a Youtube tutorial for how to get it set up correctly?

Thanks for your response, but unfortunately any guide i've seen or read says to just copy the Mother VR .dll file into the Alien Isolation folder and then just run the game. I've tried that numerous times, but the game will not load once I add that file to the game folder

Perhaps you could try running the game from its .exe in the game folder instead of running it from your STEAM library or desktop shortcut?

Maybe the reason it isn't running is because of the extra unrecognized files, and so running it without STEAM might work.

I dunno, I'm just guessing at things here because nobody else has come in to help lol. You could also try going back a few pages and reading topics on this forum - threads about VR have come up quite a few times. Maybe there's an answer for you in one of those.

Thanks again for your response. After checking on the forum on the Mother VR site, it loos as though the problem is with Windows 11. The current version of the Mod will unfortunately not work with it.

I'm really hoping for an update on the Mod cause I've been dying to play this in VR forever and just finally got a really good gaming PC to run it

I believe there is more than 1 VR mod.

Oh thanks! I'll have to do some searching

Any luck on this front? I've been trying to the MotherVR on a Win 11 computer, and I'm having the same trouble. Runs fine if I load to the desktop, but when I put the .dll file in the AI folder, the game won't launch at all. I have Steam Theatre disabled. Is Win 11 just kaput?

[decorus_veritas]

Never mind. Apparently it is broke until Nibre fixes it, or someone else tinkers with the .dll file. https://github.com/Nibre/MotherVR/issues/229

Did you write at steam launch options -steamvr? If didn't you must do that then enter the game go to options activate mother VR the game will shot down that is normal then activate steam VR and clic on Alien isilation icon at the desktop then the game should open in VR.

If that doesn't work I guess that Windows 11 really ♥♥♥♥♥♥ things... what a surprised!

I have windows 10 and it works fine for me.

Yep, I cycled through all the different seetings: placing -steamvr, turning off theatre mode, turning off steam overlay, swapping out .dll files for older versions. As soon as I take the .dll file out, the game launches fine. As soon as I put it in, it won't launch at all. I have a Win 10, but it isn't VR capable (runs the desktop version of AI great though). Desktop version of AI runs great in Win 11, but if you look at the thread I posted above, no one has reported getting it working on Win 11 yet. I'm thinking about writing Microsoft support. While they obviously can't fix the .dll file, maybe they could figure out what they changed between versions and fix *that*.

[Turambar]

In that case I'm lost... I don't understand what is avoiding you from playing it in VR and I am sorry but I don't see how to hlep you more.

[Turambar]

Have you tryed Windows compatibility options?

The issue seems to be related to some interaction between the mod and steam VR on windows 11. MotherVR works flawlessly when run on the epic store version of the game using oculus runtime. No idea why, but I can play it there no trouble. try it through steam and instant crash.

PS. Nibre isn't likely to be fixing it anytime soon, they got a job working on Halo. (probably working on some form of official implementation of their VR mod for the MC collection).

If you are on Windows 11 I ran into the same issue. Just posted a temporary solution here. https://github.com/Nibre/MotherVR/issues/229#issuecomment-1175410180
