Platforms Supported

Windows 2000 and later includes all the core support for Accessibility. Earlier versions of Windows support Accessibility to various degrees.

Platform Description of support
Windows 98 Includes Active Accessibility version 1.1 in the initial release of Windows 98; however you can run msaardk.exe to upgrade to a later version of Active Accessibility. All language versions of Windows 98 are supported, and future Windows 98 Service Packs will contain updated, localized versions of Active Accessibility.
Windows NT 4.0 Provides Limited support for Windows NT 4 with Service Pack 4 (SP4) or later. SP6 has full support and is the recommended version of NT to use for Active Accessibility. To use Active Accessibility, you must run msaardk.exe to install the Active Accessibility core system components. The msaardk.exe package fails if SP4 (or later) is not already installed. Only Intel architecture is supported.
Windows 2000 Includes the Active Accessibility core system files for all language versions of the operating system. Support for both Intel and Alpha processors is provided in Windows 2000.
Windows Me Accessibility options are installed by default during Windows Me setup, making the Accessibility Wizard and accessibility utilities instantly available. The increased integration of Microsoft Active Accessibility in Windows Me helps make many accessibility aids run more smoothly and effectively with the operating system and other applications.
