AspNet5.ENU.RC1安装错误：0x80072f0d - 未指定的错误

AspNet5.ENU.RC1安装错误：0x80072f0d - 未指定的错误

操作系统：Windows 7 x64

安装文件：AspNet5.ENU.RC1_Update1_KB3137909.exe

安装过程中提示需要：Microsoft .NET Framework 4.5.1，如下图：

Microsoft .NET Framework 4.5.1（脱机安装程序）下载地址：

https://www.microsoft.com/zh-cn/download/details.aspx?id=40779
https://www.microsoft.com/zh-cn/download/confirmation.aspx?id=40779
适用于 Windows Vista SP2、Windows 7 SP1、Windows 8、Windows Server 2008 SP2 Windows Server 2008 R2 SP1 和 Windows Server 2012 的 Microsoft .NET Framework 4.5.1（脱机安装程序）

但是我并没有安装Microsoft .NET Framework 4.5.1，而是下载安装了Visual Studio 2015，

安装了Visual Studio 2015之后以为就不需要安装AspNet5，但是在创建AspNet5的项目时却直接打开一个下载链接，下载AspNet5安装程序。

下载后安装过程中就提示0x80072f0d - 未指定的错误。

点击“log file”部分错误内容如下：

发现是有文件下载不成功，考虑到当时正在使用下载工具下载大文件，把带宽都点满了，嗯嗯，应该是这个问题，于是把下载工具关了，再重新运行安装程序，OK，安装成功了。
