Thank you for pointing this out. We've adapted the KB.
The space mouse is not yet supported with the Rhino plugin.
We are currently working together with 3dConnexion to include this feature,
but it won't make it to the v2.1 release, I'm afraid.
Fortunately, it's already supported in 188.8.131.524.
We published the manual for the installer program options here:
As you can see, switches like /RHINO=0|1, /REVIT=0|1 or /SKETCHUP=0|1 already work in exactly the way you suggested.
Let us know if you like it.
