P3D v4.4.16.27077 here. LIMN opens without troubles at my side, using ADE v01.76.6715. You should possibly update ADE to latest version.
Checking the path of your P3D4, it looks as it is installed inside one of the standard Microsoft Program folders that are heavily controlled by the system about read and write rights by the user. Suggest you check your UAC and lower the control level, or manage, next time or next update, to install your flightsimming related softwares (including ADE) outside the Program Files (x86) or Program Files folders.
Just my 2 cents
