MySql安装并重新安装，但不起作用

在我的Windows10上，我安装了一个旧的mySql。我按照教程卸载了它，在“控制面板”->“软件安装”中，我卸载了仅以mysql名称开始的所有项目，在这个阶段，我看到我的Sql Connector 8.0.16在按下卸载按钮、确认并等待消息后，再次出现在列表中

然后，我重新启动了计算机，下载了mysql-installer-community-8.0.18.0并执行。首先，我看到了一条欢迎回来的消息，但我已经全部卸载了。而且，在可用项目列表中，我看到windows select要升级的产品，然后只有一个连接器/网络，没有其他东西。但我不想要它，我想要重新安装整个mysql

当然，mySql还没有完全卸载。我怎样才能解决这个问题？你有没有一个更强大的程序来真正卸载整个mysql，或者你能建议我执行上一篇教程中没有的其他步骤

编辑：删除2次注册表项后，重新启动计算机并重新安装，最终工作！仅在Connector/.NET组件中看到以下错误。我无法卸载或升级它

编辑：我也在mysql官方论坛上问过，但几天后我的问题还没有得到论坛工作人员的批准。我不知道原因。

1从任务管理器中查找已执行的服务或exe。注意：如果您没有找到任何东西，那么请成功卸载Mysql

2打开文件位置并记住

3然后从任务管理器停止mysql服务或exe

---

并且还可以从文件夹中删除文件，该文件夹位于我之前告诉过的文件夹位置，请记住。

根据，您可能还需要删除程序和AppData目录中的MySQL目录。如前所述，这正是我所做的。啊，不，我做的远远不止这个链接！但它不起作用。你能建议我采取上面没有提到的步骤吗？感谢您的时间广告，感谢您的帮助。可能它在HKEY_CURRENT_USER\Software\MySQL AB或HKEY_LOCAL_MACHINE\Software\MySQL AB中留下了注册表项。请参见否，不起作用。我也看到了同样的情况。我还在我的原始帖子中复制了安装程序的整个输出消息，在安装过程之后我看到了这一点。我绝望了。它发生在哪里？只是删除链接？非常感谢，现在我几乎解决了这个问题。我已经完成了你写的操作。我只应该解决一个连接器/网络问题，我用完整的日志更新原始问题。你能看见吗？感谢
