嗨Greeshma，

Hi Greeshma,

即使我面对这种情况很多次。我以前唯一一次重新安装操作系统。但要确保你的控制器工作正常意味着hck客户端应安装在你的至少一个设置上。

Even i faced such situations many times. The only thing I used to do reinstallation of OS. but be sure that your controller is working fine means the hck client should install on atleast one of your setup.

谢谢，
