因为你的问题是Visual Studio安装而不是开发人员文档和帮助系统（这个论坛主题），请考虑在Visual Studio安装论坛上发帖，这里：

As your issue is with Visual Studio setup and not about the Developer Documentation and Help System (this forum's topic), please consider posting in the forum for Visual Studio setup, here:

重新发布时，请包括哪个Windows您正在安装的版本，以及错误消息的完整引用。

When you repost, please include which Windows version you are installing under, and a full quote of the error message.
