Adobe Flash Player Debugger provides access to debug players and content debuggers and Standalone Players for Flex and Flash Developers.

Updated debugger and standalone versions of Flash Player. These versions contain fixes for critical vulnerabilities identified in Security Bulletin APSB 16-25. The latest versions are 22.0.0.209 (Mac & Win NPAPI & PPAPI); 22.0.0.210 (Win ActiveX) and 11.2.202.632 (Linux). All users are encouraged to update to these latest versions.

Uninstalling the Windows 8.1/8.1 ActiveX debuger: please note the KB number in the installer filename after downloading the installer file. To uninstall the debugger, go to Control Panel > Programs > Programs and Features > Installed Updates. Look for the entry with the KB number the same as in the installer file and uninstall that update.

What is the extended support release?
Adobe makes available a version of Flash Player called the “Extended Support Release” (ESR) to organizations that prefer Flash Player stability over new functionality. “We have created a branch of the Flash Player code that we keep up to date with all of the latest security updates, but none of the new features or bug fixes available in our current release branch”. This allows organizations to certify and stay secure on Flash Player with minimal effort.
