突然关闭后无法安装Visual Studio 2017社区版 [英] Cannot install Visual Studio 2017 community edition after sudden shutdown

问题描述

我开始安装VS，然后由于过热而突然关闭计算机.

I started installing VS and then my computer turned off suddenly (due to overheating).

当我重新安装它时，出现一条错误消息，提示:

When I was reinstalling it, an error message appeared saying:

Can't install in a non empty folder.

所以我删除了文件夹C:\ Program Files(x86)\ Microsoft Visual Studio \ 2017 \ community

So I deleted the folder C:\Program Files (x86)\Microsoft Visual Studio\2017\community

然后，当我尝试安装它时，它失败了.

Then, when I tried to install it, it failed.

这是日志:
