nw V0.15 无法发布！?报错

@RogerWang 你好，想跟你请教个问题：

@newwell 你好，想跟你请教个问题：我想用nwjs nwjs-v0.15.0-win-x64,进行程序发布，但是总是不成功（现象为只启了4个进程，没有弹出nw浏览器）。同样的配置和方法在v0.12.3可以。您能帮解答下吗？

	方法为：
</p>
<p style="font-size:13.3333330154419px;">
	1.在<span style="font-size:13.3333330154419px;">nwjs-v0.15.0-win-x64文件夹下建我的程序包 testapp，里面放程序包，app.js,package.json(他两个在跟目录)，</span>
</p>
<p style="font-size:13.3333330154419px;">
	<span style="font-size:13.3333330154419px;">2.在<span style="font-size:13.3333330154419px;">nwjs-v0.15.0-win-x64下和nw.exe同级放package.json，为nw.exe 创建快捷方式，并且在快捷路径后添加我的 testapp。</span></span>
