I am trying to purchase 3D Analyst. I currently have ArcGIS Pro Basic and ArcGIS Desktop, licensed to one user (myself) within my organization. When I add it to my cart, this error pops up and won't let me check out. I use ArcGIS Pro and Desktop both, so I don't know why it thinks I don't have a license to use this. Any ideas?
It would be wise to connect with your local Esri Distributor or Esri for more clarification and software purchase.
I am not suggesting anything else, for now.
