SONAR X3 Producer can't find my Roland XP-80

I just installed SONAR X3 Producer on a new computer. I had SONAR X1 Studio on my old computer, which died recently, and I don't remember how I did it but I had all 16 MIDI channels setup to recognize my XP-80, KORG Wavestation and Kurzweil 2500S. SONAR X1 had pre-loaded ins files for all 3 of these synths (including the 4 expansion boards on my XP-80), but I can't find them.
 
I tried clicking on "Roland GS" in the "Uses Instrument" pane, and then on "Import" in the "Define Instruments and Names, and I assumed that the ins files would be somewhere in the Program Files folder but I couldn't find any.
 
So how do I get the ins file going?
 
Thanks,
John
