That sounds like a problem of your device. Where do you want to install it?
Intel 5820K OC@4Ghz, Titan X (Maxwell), 32GB Corsair Vengeance DDR4, ASRock X99 Taichi, Samsung 500Gb 960 Evo M.2, Corsair H100i v2 Cooler, Inateck KTU3FR-4P USB 3 card, Windows 10 Pro v20H2 (19042.964)
heres a link that i follwed tonight http://thedailydeveloper.com/step-by-step-how-to-fix-oculus-not-enough-space-install-error/
i folowed it pretty easily but it didnt work so I kept reading forums..... heres what worked i went back and reread the step by step at the very bottom the OP says hit the SPACE BAR. i did that it deletes the entire line so i figured maybe hes trying to say to us idiots... put a space in between drive:O oculusSetup.exe and /drive=O the trick was making sure there is a cursor space between the exe and yoru new drive that you made.
