Adobe previews 64-bit Flash with IE9 support

Adobe® Flash® Player "Square" is a preview release that enables native 64-bit support on Linux, Mac OS, and Windows operating systems, as well as enhanced support for Microsoft Internet Explorer 9 beta.

We have made this preview available so that users can test existing content and new platforms for compatibility and stability. Because this is a preview version of Flash Player, we don’t expect it to be as stable as a final release version of Flash Player. Use caution when installing Flash Player "Square" on production machines.

The key new capabilities in the Flash Player "Square" preview are:

64-bit support — Native support for 64-bit operating systems and 64-bit web browsers on Linux, Mac OS, and Windows.

Internet Explorer 9 hardware accelerated rendering support — Enhanced support for Internet Explorer 9 Beta. It takes advantage of hardware accelerated graphics in Internet Explorer 9 Beta, utilizing hardware rendering surfaces to improve graphics performance and enable seamless composition.

The following known issues exist in Flash Player “Square”:

Video playback issues may appear on certain websites such as Hulu.com, Audi.co.uk, and nbc.com.

Content protection using Adobe Flash Access is not currently supported on 64-bit platforms in this preview release.

Mouse interactivity in the Settings UI dialog does not work using Internet Explorer 9. Keyboard navigation works as expected. Please pardon our dust.

Internet Explorer 9 is not yet final. As such, Adobe is continuing to work with Microsoft to resolve critical issues before the final release of Internet Explorer 9.

This release will not receive automatic update notifications, and users will need to manually uninstall this preview before installing a standard shipping release of Flash Player
