将这两项卸载，然后按照视频里介绍的步骤下载MySQL 5.7版本

尝试了多种方法，还是安装不成功。

报错信息如图如下

参照网友文章修改配置文件，或者把MySQL彻底卸载，再把ProgramData下的整个MySQL文件夹都删了，然后重新装。

80和57的权衡下来，研究了两天，各种改N次，看了很多关于用80改接口的文章，为保证软件正常运行，用80,难度系数大，改得更多，以后还不知道出什么问题，而系统还是不能正常安装57MSI ，于是决定手动安装压缩版进WIN10，对于不能启动服务的项目修改INI通过，现才能正常使用案例，感谢老师，也希望明日科技能推出适合80版的案例。

我们将来会计划推出兼容多版本的数据库接口，你现在也可以尝试安装5.6或5.5版本，驱动和5.7是一样的。

谢谢老师，期待更好的版本，也祝明日科技发展得更好。
