If you’re using Chromium based Vivaldi or Opera. Visit Flash Player help page and click check now button, the page displays version of Flash player along with names of your browser and Operating System. Go back to the page with the Flash content. The Flash player about page lists latest Flash Player version for all browsers. If you see 'Component not updated' or 'Component updated,' you're on the latest version. Look for 'Adobe Flash Player.' Click Check for update. And according to, Flex 4.6 sets target-player to 11.1 and swf-version to 14. In the address bar at the top, enter chrome://components and press Enter. This means shows 11 for my SWF, even though I only require users to have 10.2. For the SDK version I'm using (4.5.1), the defaults are as follows: Adobe Flash Player is designed to play multimedia contents including video, audio, 3D graphics and raster graphics and supports MP3, FLV, PNG, JPEG and GIF (Need to convert FLV to MP4, try MiniTool MovieMaker). It will take you to a web page that tells you the exact version you have installed. The default values for these options can be found inside FLEX_SDK/frameworks/flex-config.xml. How do I check my Flash player version in Chrome Right click on a flash object and choose the last item from the menu, which is usually something like About Adobe Flash Player X. Although Flash Player is less common on mobile devices, this page can still let mobile device users know whether Flash is available in their browser. The minimum player version is set at compile time through the compiler option target-player, while the SWF file format version is set through the option swf-version. The panel below tells you if you have Flash Player installed, what version you have, if it is a debug(developer) version, and if there is a newer version available. That is not the same as the target player version. Most - all? - of the answers so far are incorrect, which is unfortunate as I was hoping to find an answer to this question :).īyte 4 of the SWF indicates what version of the SWF file format is used by the SWF.
