So, we'll need some more info.
Does anything get installed anywhere? If so what gets installed where? I'd like to know the sound library path as well as the install location of any S2 plugin. If you don't know any plugin install location, do a search in Windows for the superior drummer.dll
Check the install locations in the FAQ below.
