bluestacks 模拟器安装不上

　　故障现象:

　　以前安装过该软件，但是卸载了之后再次安装的时候就有报错：

　　uh oh-bluestacks cannot be installed on this pc because you already have another program

　　that uses a 'dock' (friendly control bar along the side of your screen) you'll need to

　　uninstall this other program before bluestacks will install successfully email us at

　　[email protected] if you need any help thanks

　　原因分析:

　　之前卸载的不干净，删除之前残留的注册表项就可以了。

　　解决方案:

　　删除注册表[HKEY_CURRENT_USERSoftwareRocketDock]的所有项值，问题解决。

　　备注:

　　删除注册表操作有风险，请慎重操作。
