MySql取消安装并重新安装，但不起作用

标签： mysql

在Windows 10上，我安装了旧的mySql。我按照this教程进行了卸载，并从控制面板->软件安装中，卸载了所有以mysql开头的项目（仅，在此阶段，我看到My Sql Connector 8.0.16在“卸载”之后）按钮，确认并等待消息，再次出现在列表中。

然后，我重新启动计算机，并下载了mysql-installer-community-8.0.18.0并执行了。首先，我看到了“欢迎回来”消息（但是我已经全部卸载了）。并且，在可用项目的列表中，我看到窗口“选择要升级的产品”，然后只有连接器/ NET，没有其他任何东西。但是我不想要它，我想要整个mysql重新安装。

当然，mySql尚未完全卸载。我该如何解决这个问题？您是否有一个功能更强大的过程可以真正卸载整个mysql，或者您可以向我建议我已经遵循的上一教程中未介绍的其他步骤？

编辑：两次删除reg键后，重新启动计算机并重新安装，终于可以了！仅，我通过“ Connector / .NET”组件看到以下错误。我无法卸载或升级它。

编辑：我也在官方的mysql论坛中问过，但是几天后，我的问题尚未得到论坛工作人员的认可。我不知道原因。

1 个答案:

答案 0 :(得分：1)

1）从任务管理器中找到执行的服务或exe。注意：（如果找不到任何东西，则可以成功完成Mysql的卸载）

2）打开文件位置并记住。

3）然后从任务管理器中停止mysql服务或exe  并从文件夹中删除文件夹中存在的文件（我之前曾告诉我记得这样做过）。
