DotNetBrowser supports Adobe Flash plugin and can display Flash content. In order to display Flash contents you need to download and install Flash Player. Flash content is displayed in windowless mode, so make sure that Flash content you display on the web page really supports this mode.


NPAPI & PPAPI Plugins

Note: Since April 2015 Google Chrome stopped supporting NPAPI plugins.

Previous DotNetBrowser versions still support NPAPI plugins, but since version 1.7 NPAPI plugins are no longer supported.

We recommend that you download and install Flash PPAPI plugin.


Starting from version 1.18, DotNetBrowser includes both Chromium 64-bit and 32-bit binaries. Therefore, the corresponding PPAPI plugin is used depending on the Chromium engine architecture.


To download Flash PPAPI plugin go to https://get.adobe.com/flashplayer/otherversions, select your operating system and PPAPI plugin version in the second dropdown menu as shown below:


DotNetBrowser will automatically find installed Flash PPAPI plugin and use it to display Flash content. 


It is also possible to specify path to the Flash Player PPAPI plugin using the following approach:


BrowserPreferences.SetChromiumSwitches(
    "--ppapi-flash-path=\"<path_to_plugin_DLL>\"", 
    "--ppapi-flash-version=<plugin_version>"
);
