Hmm.. I didn't change anything during install. Just clicked go-ahead all the way.
but changing anything during install shouldn't make a difference, though? However, after it's set it's hardcoded into the instrument or something. At least that is how it used to be with Rapture and DimPro. Since this is a new instrument I would imagine that whenever you select a destination during install, then it will actually look for stuff there.
I can see the samples and all that in the directory for instruments and samples, but they won't show up in the instrument. I'm still a mac n00b but to me it seems like RaPro won't register the programs.
