What Daniel says works perfectly for me. I bought the boxed version with the USB-eLicenser and I just plug in the dongle to whatever computer I am in front of. (I put the dongle on a lanyard because it is pretty small). I am a teacher, and I teach at 2 different schools, so I run Dorico on whichever school I am at, plus a laptop for use at home and on the road. I keep all my files on a Dropbox account so I’m always using the latest files for my music projects.
