Question

it found 3rd party rewire but not superior drummer.

Answer 1

Are you looking in VST, or instruments. SD should be listed in instruments. You may also have to tell S1 in setup where to look for vst files. Third thing to check, which version of SD is installed? A 32bit instrument will only show in the 32bit version of S1, and 64 bit needs a 64bit daw.
