FlashDevelop调试Air出错

按下F5调试命令行窗口出现错误：

Starting AIR Debug Launcher...

invalid application descriptor: Unknown namespace: http://ns.adobe.com/air/application/18.0

打开application.xml

修改

<application xmlns="http://ns.adobe.com/air/application/18.0">

改为

<application xmlns="http://ns.adobe.com/air/application/17.0">

问题解决
