title: Can't run pepper flash plugin inside my electron app
body: <p>I try to run flash inside my electron application, so I followed next instructions from <a href="https://github.com/electron/electron/blob/master/docs/tutorial/using-pepper-flash-plugin.md" rel="nofollow noreferrer">https://github.com/electron/electron/blob/master/docs/tutorial/using-pepper-flash-plugin.md</a> and I did next steps:</p>
  
  <ol>
  <li>Copy and paste from Chrome to my project directory <strong>PepperFlashPlayer.plugin</strong> version <strong>27.0.0.130</strong> (I take version from info.plist inside plugin)</li>
  <li><p>Copy and use inside my project next code:</p>
  
  <pre><code>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, 'PepperFlashPlayer.plugin'));
  </code></pre></li>
  </ol>
  
  <p>and:</p>
  
  <pre><code>mainWindow = new BrowserWindow({
      width: 800,
      height: 600,
      fullscreen: true,
      webPreferences: {
        nodeIntegration: false,
        plugins: true,
      }
    });
  </code></pre>
  
  <p>When I launch the application i see the next error: <strong>You must have Adobe Flash Player 11.3.300 or higher installed in your system. Click here to visit Adobe.com now</strong></p>
  
  <p>If I inside also <code>app.commandLine.appendSwitch('ppapi-flash-version', '27.0.0.130')</code> the application says: <strong>couldn't load plugin</strong> inside a black screen.</p>
  
  <p><code>chrome://plugins</code> doesn't work in current chrome version. I also tried to install flash plugins (system version of flash is also 27.0 version)</p>
  
  <p>Did anyone met this problem and can help me?</p>
