安装MYSQL出错：a windows service with the name MYSQL already...service解决

今天把mysql5.1卸载了，想装个5.5，安装时提示：a windows service with the name MYSQL already exists.Please uninstall this service correctly or choose a different name for the new service.

可以尝试删除残留的注册表信息HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services下面找到MySQL注册表信息把它整个删掉后，重装mysql成功了！

过了这步到启动service时又提示：Cannot create windows service for mysql.error:0

WIN+R进入CMD命令行：

C:/Users/Stone>sc delete mysql

[SC] DeleteService 成功

C:/Users/Stone>

之后就搞定了！
