I've just installed ARC GIS 10.5.1, where is the tutorial data? Do I have to download it from a website?
There is a Tutorial Data setup available from MyEsri.
Where exactly is the Tutorial Data setup in MyEsri?
Adding tutorial data—Help | ArcGIS Desktop
Click My Organizations and then click Downloads.
Click Data and Content and then navigate to the ArcGIS Desktop tutorial data set and click Download
Unfortunately I'm not seeing "downloads" in MyEsri, nor if I click Help | ArcGIS Desktop. Perhaps the route to finding tutorials is different when you're on a trial version?
