HELP, Electron flash player will not load


Hey everyone,

I have to make a desktop app from an existing website on a very tight deadline and I cannot get flash player working.
I copied my PepperFlashPlayer.plugin to the root of my project (working on mac OSX), and referenced it in my js.

This is my code

    var app = require('app');  // Module to control application life.
var BrowserWindow = require('browser-window');  // Module to create native browser window.

// Report crashes to our server.

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the javascript object is GCed.
var mainWindow = null;

// Quit when all windows are closed.
app.on('window-all-closed', function() {
    // On OSX it is common for applications and their menu bar
    // to stay active until the user quits explicitly with Cmd + Q
    if (process.platform != 'darwin') {

// Specify flash path.
// On Windows, it might be /path/to/pepflashplayer.dll
// On Mac, /path/to/PepperFlashPlayer.plugin
// On Linux, /path/to/
app.commandLine.appendSwitch('ppapi-flash-path', './PepperFlashPlayer.plugin');

// Specify flash version, for example, v17.0.0.169
app.commandLine.appendSwitch('ppapi-flash-version', '');

// This method will be called when Electron has done everything
// initialization and ready for creating browser windows.
app.on('ready', function() {
    // Create the browser window.
    mainWindow = new BrowserWindow({
        'width': 1440,
        'height': 756,
        "node-integration": false,
        'web-preferences': {
            'plugins': true

    // and load the index.html of the app.

    // Open the devtools.

    // Emitted when the window is closed.
    mainWindow.on('closed', function() {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        mainWindow = null;
