Supported configurations

The Flash Player uses a technology called Microsoft Active Accessibility (MSAA) to communicate with screen readers. MSAA provides a highly descriptive and standardized way for applications and screen readers to communicate. MSAA is available on Windows operating systems only. See the Macromedia Flash Accessibility Web page for more information about Windows operating systems that support MSAA.

The Windows ActiveX (Internet Explorer plug-in) version of Flash Player 6 supports MSAA, but the Windows Netscape and Windows stand-alone players do not.

MSAA is currently not supported in the opaque windowless and transparent windowless modes. (These modes are options in the HTML Publish Settings panel, available for use with the Windows version of Internet Explorer 4.0 or later, with the Flash ActiveX control.) For information about these modes, see Setting publish settings for HTML documents accompanying Flash movies. If you need your Flash movies to be accessible to screen readers, avoid using these modes.
