Trying to compile a vive project on 4.11p7
I’m getting this message a lot in huge blocks
Does instanced stereo rendering not work on a 64bit build?
Should I be doing 32bit builds?

Check your Project Settings -> Platforms -> Windows and under Targeted RHIs, make sure only DirectX 11 (SM5) is selected. I believe by default it attempts to target DX10 as well, which does not support instanced stereo rendering. This may be what is giving you the error

Thank you - I had the same issue, and this indeed fixed it.
