Flex Builder3调试运行提示没有安装Flash Player

Flex Builder3调试运行提示：

C:\Users\Administrator.WIN7-1808211811\AppData\Roaming\360se6\Application\plugins\NPSWF32.dll

Flex Builder cannot locate the required version of Flash Player. You might need to install Flash Player 9 or reinstall Flex Builder.

Do you want to try to run your application with the current version?

又安装了一次debug版本的flash player，调试还是不行，默认浏览器是360，修改调试浏览器为IE，设置如下：

Window-Preferences-General-Web Browser中选择Internet Explorer即可。
