想在win7+EF6 + VS2017 + MySQL 但是安装 MySQL  for  Visual Studio 1.2.7 时一直安装不上去，如下：

Action 9:40:05: InstallFinalize.
1: Action 9:40:05: DeleteRegKeyAndExtensionsFile_VS2013.

以上使用的是mysql-installer-community-5.7.21.0.msi 这个来安装的，

单独使用mysql-for-visualstudio-1.2.7.msi （此处去掉勾选安装for  vs2012）安装并查看日志如下：

搞了三天了，看了官方论坛貌似也没找到好的解决办法，相同的问题stackover flow

有大神遇到过这样的问题么，有啥解决办法不？
