# Using Pepper Flash Plugin
 | 
						|
 | 
						|
Electron supports the Pepper Flash plugin. To use the Pepper Flash plugin in
 | 
						|
Electron, you should manually specify the location of the Pepper Flash plugin
 | 
						|
and then enable it in your application.
 | 
						|
 | 
						|
## Prepare a Copy of Flash Plugin
 | 
						|
 | 
						|
On macOS and Linux, the details of the Pepper Flash plugin can be found by
 | 
						|
navigating to `chrome://plugins` in the Chrome browser. Its location and version
 | 
						|
are useful for Electron's Pepper Flash support. You can also copy it to another
 | 
						|
location.
 | 
						|
 | 
						|
## Add Electron Switch
 | 
						|
 | 
						|
You can directly add `--ppapi-flash-path` and `--ppapi-flash-version` to the
 | 
						|
Electron command line or by using the `app.commandLine.appendSwitch` method
 | 
						|
before the app ready event. Also, turn on `plugins` option of `BrowserWindow`.
 | 
						|
 | 
						|
For example:
 | 
						|
 | 
						|
```javascript
 | 
						|
const {app, BrowserWindow} = require('electron')
 | 
						|
const path = require('path')
 | 
						|
 | 
						|
// Specify flash path, supposing it is placed in the same directory with main.js.
 | 
						|
let pluginName
 | 
						|
switch (process.platform) {
 | 
						|
  case 'win32':
 | 
						|
    pluginName = 'pepflashplayer.dll'
 | 
						|
    break
 | 
						|
  case 'darwin':
 | 
						|
    pluginName = 'PepperFlashPlayer.plugin'
 | 
						|
    break
 | 
						|
  case 'linux':
 | 
						|
    pluginName = 'libpepflashplayer.so'
 | 
						|
    break
 | 
						|
}
 | 
						|
app.commandLine.appendSwitch('ppapi-flash-path', path.join(__dirname, pluginName))
 | 
						|
 | 
						|
// Optional: Specify flash version, for example, v17.0.0.169
 | 
						|
app.commandLine.appendSwitch('ppapi-flash-version', '17.0.0.169')
 | 
						|
 | 
						|
app.on('ready', () => {
 | 
						|
  let win = new BrowserWindow({
 | 
						|
    width: 800,
 | 
						|
    height: 600,
 | 
						|
    webPreferences: {
 | 
						|
      plugins: true
 | 
						|
    }
 | 
						|
  })
 | 
						|
  win.loadURL(`file://${__dirname}/index.html`)
 | 
						|
  // Something else
 | 
						|
})
 | 
						|
```
 | 
						|
 | 
						|
You can also try loading the system wide Pepper Flash plugin instead of shipping
 | 
						|
the plugins yourself, its path can be received by calling
 | 
						|
`app.getPath('pepperFlashSystemPlugin')`.
 | 
						|
 | 
						|
## Enable Flash Plugin in a `<webview>` Tag
 | 
						|
 | 
						|
Add `plugins` attribute to `<webview>` tag.
 | 
						|
 | 
						|
```html
 | 
						|
<webview src="http://www.adobe.com/software/flash/about/" plugins></webview>
 | 
						|
```
 | 
						|
 | 
						|
## Troubleshooting
 | 
						|
 | 
						|
You can check if Pepper Flash plugin was loaded by inspecting
 | 
						|
`navigator.plugins` in the console of devtools (although you can't know if the
 | 
						|
plugin's path is correct).
 | 
						|
 | 
						|
The architecture of Pepper Flash plugin has to match Electron's one. On Windows,
 | 
						|
a common error is to use 32bit version of Flash plugin against 64bit version of
 | 
						|
Electron.
 | 
						|
 | 
						|
On Windows the path passed to `--ppapi-flash-path` has to use `\` as path
 | 
						|
delimiter, using POSIX-style paths will not work.
