My apologies if I've posted this in the wrong category -- feel free to move it as necessary.
I own the original Motif Rack. I don't think it's an ES, but correct me if I'm wrong.
Years ago, I used to have the Multi Editor, but I can't seem to find the right download location. It's probably under my nose, but all I could find was MOTIF RACK_Multi Part Editor V216.
I downloaded this to my old 2007 MacBook Pro running El Capitan 10.11.6, and placed the .DMG file on my desktop, but after a couple of steps, it error out saying that there was no software to install (see attached).
I do have Studio Manager 2 installed, and it appears to be working correctly.
What am I missing?
