You need at least 1.65, and if you look at the mod's notes, they list 1.67.
I'm running 1.65 with SOL 2.0 in VR without any notable issues. i7 7700k, GTX 1080 Ti, Windows 10.
Ok. I prefer not to use buggy versions of CSP because I’ve had a bunch of weird issues in the past, so I suppose I’ll hold off until the stable versions catch up to use the showroom on this one.
