Repairing Active Accessibility support
This page describes how to diagnose and repair issues caused by broken Active Accessibility support.
The Active Accessibility support can be broken after:
- Installing certain Windows updates
- Uninstalling/upgrading certain applications such as Adobe Acrobat Reader or Microsoft Office
Selectors are not generated for applications relying on the
IAccessible registry entries, such as File Explorer, Internet Explorer or Microsoft Office.
For example, when using UI Explorer to indicate UI elements in Windows File Explorer, instead of individual elements, the entire area is selected.
Following a Windows update,
IAccessible registry entries were overwritten and became corrupted.
The accessibility support provided through registry configuration can also get broken when some applications (such as Adobe
Acrobat Reader) register custom implementations for
IAccessible, but don’t restore default settings on uninstall/upgrade.
Note: Changing registry entries might affect the functionality of your machine! It is recommended to create a backup first, as
explained on this page.
In order to check if
IAccessible registry entries became corrupted, you need to open the Windows Registry Editor and verify whether the following keys are
missing or have other values, and add/modify them if necessary.
Below are the values that should be present in the registry.
