FIX: This site uses a plugin (Adobe Flash Player) that will soon be unsupported – Could not load Shockwave flash in Chrome (Solved)

Today one of my customers called me to report the following Chrome problem when he opened websites that use the Adobe Flash Player or Shockwave Flash plugin (e.g. YouTube, Facebook, etc.): "This site uses a plugin (Adobe Flash Player) that will soon be unsupported – Could not load Shockwave flash". After doing some research, I discovered that from Chrome version 42 and higher, all websites or services that use NPAPI* plugins (e.g.: Silverlight, Facebook, Java, Unity, Google Earth, Google Talk, etc) will not be supported (won't work) anymore. On the other hand, all websites and services that use PPAPI** plugins (including the Chrome shipped plugins e.g. Adobe Flash, PDF Viewer, etc.) will continue to work.

The strange thing with the Adobe Flash or Shockwave Player loading problems, is that the most secure versions (PPAPI) of these plugins  are already included in the latest Chrome versions installations so the problem could occur if Chrome loads an unsupported NPAPI plugin. In this tutorial you can learn how to resolve and bypass the Adobe Flash Player or/and shockwave load problems in your Google Chrome browser.

* NPAPI (Netscape Plugin Application Programming Interface) plugins have the full permissions of the current user and are not sandboxed or shielded from malicious inputs by Google Chrome.
** PPAPI (Pepper Plugin Application Programming Interface) plugins have limited permissions of the current user and they are more secure.

How to solve This site uses a plugin (Adobe Flash Player) that will soon be unsupported – Could not load Shockwave flash (Problem in Chrome).

Solution 1. Enable NPAPI Plugin support.

Solution 2. Disable Adobe Flash Player plugin.

Solution 1. Enable NPAPI plugin support on Chrome.

The first solution is to enable the NPAPI support on your Chrome browser. Keep in mind that this solution is temporary and will work up to version 45 of Chrome, because after that version (45), all NPAPI plugins will be totally disabled. If you want to use NPAPI plugins after version 45, you have two options: To use an alternative browser (like Internet Explorer, Firefox, etc.) or to completely uninstall Chrome (Version 45 or higher) and then to download and install an older version of Chrome browser. (After installation you must disable the automatic Chrome update).

1. Open your Chrome browser and at the address bar paste the following command and press Enter:

  • chrome://flags/#enable-npapi

Solution 2. Disable Adobe Flash Player plugin in Chrome.

The "This site uses a plugin (Adobe Flash Player) that will soon be unsupported" or/and "Could not load Shockwave flash" problems can happen because Chrome loads two different versions of Flash player (or Shockwave) plugins every time it starts. In such situations, the solution to bypass the flash/shockwave player loading problems, is to disable the oldest version of these plugins (Flash Player or Shockwave Player) from Chrome Plugins.

1. Open your Chrome browser and at the address bar paste the following command and press Enter:

  • chrome://plugins

2. At the listed plugins, find if you have two versions of the same plugin. Then disable the oldest one. In the case that you have only one version of the Flash Player or Shockwave plugins (like the screenshot bellow) then disable that version.
