Just tried it, it works for me. I use
Multistage2015_forOrbiter2016
spacecraft4
(they are downwards compatible)
There is a bug with the old SLC41 not showing up in the MRO scenarios:
This can be corrected by installing the
VulcanCentaur addon after MRO.
It overwrites the old SLC41 and contains the correct cfg and dll of SLC41.
