Links to the ArcObjects Developer Help from the ArcGIS Desktop Help do not work

Description

Note:
This article pertains to ArcGIS versions 9.x only. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools.

In the ArcGIS Desktop Help system, links to the ArcObjects Developer Help sometimes do not work when clicked. When the links are clicked more than once, the ArcGIS application from which the Help was accessed often stops responding.

Cause

This is caused by a bug that exists in Internet Explorer version 5.5 Service Pack 1. The bug causes improper shortcuts in HTML Help.

Note:
As neither Esri Support nor Microsoft will continue to support Internet Explorer, Esri strongly recommends switching to a modern browser, such as Microsoft Edge, Mozilla Firefox, or Google Chrome. For more information please refer to ArcGIS Blog: So Long Internet Explorer 11, and Thanks for All the Views  and Microsoft 365 Blog: Microsoft 365 apps say farewell to Internet Explorer 11 and Windows 10 sunsets Microsoft Edge Legacy.

Solution or Workaround

You have two options to avoiding this issue.

Access the Help directly from disk

Browse to <install_drive>:\arcgis\arcexe82\ArcObjects Developer Kit\Help and double-click 'AODev.chm' to launch the ArcObjects Developer Help system.

Note:
To make this file more easily accessible you may want to create a shortcut on your desktop.
