Hello. I purchased the book GTK ArcGIS pro and am attempting to activate the software. I activated ArcGIS desktop alright, but get errors when I run Pro. I see one needs a license attached to the account, but I don't belong to an organization and there's no page for the 180 day trial, only the 21 day trial. I read that trials are not activated in my esri, but no trial page fits the 180 day trial scenario. I've read the other posters re: arcgis pro, but those are paid accounts and they don't work through organization. Thanks!
