When I look at this documentation, it seems like I should have this list of styles included in my install. However, I only have "ArcGIS 2D" and "ArcGIS 3D" included in my installation (See image). Do I need to do something additional to install these additional styles? I found this reference that seems to indicate that maybe they are not included by default, but if you go to the gallery as it describes, there are only PDFs there and not the stylx files.
Solved! Go to Solution.
I had to uninstall and reinstall the same version (3.3) to fix the problem.
