I'm on a personal laptop, where my account is already Administrator, there are no other user accounts. Just my user name and Public.
The keyboard shortcuts are good if I start InDesign with 'Run as Administrator'. But I don't want to have to remember to do that every time I use it.
Your instructions say to go into two different user areas, but I only have one - my user account (which is already Administrator) and Public - which doesn't have an AppData folder in it.
