The offline help system opens in the ArcGIS Pro Help viewer application. The offline help system matches your installed version of ArcGIS Pro. For example, if you use ArcGIS Pro 3.1, the offline help system topics apply to ArcGIS Pro 3.1.
As with the online help system, the Help viewer presents a table of contents on one side of the page and corresponding help topics on the other. Unlike the online help, it doesn't use horizontal tabs to categorize topics by theme.
Browse the table of contents or search for topics by keyword using the search text box in the upper corner of the viewer.
Note:
Compact help is an additional help system that is included when you install ArcGIS Pro. It contains a small number of topics, primarily related to setting up and licensing the application. If you open the help from the application and neither the online nor offline help system is available, the compact help system opens instead. The compact help system opens in a browser tab as a local file.
