解决办法：

VC2015、VC14 在 Windows 2012 R2 安装失败,0x80240017 - 未指定的错误，解决办法
据朋友反应VC2013一样存在这个问题……

查资料说是没有安装 KB2999226 补丁，查看错误日志文件，里面有一行C:\ProgramData\Package Cache\FC6260C33678BB17FB8B88536C476B4015B7C5E9\packages\Patch\x64\Windows8.1-KB2999226-x64.msu" /quiet /norestart'

可见，该补丁是带了的，而它安装失败，直接去点击这个补丁，弹出错误：此更新不适用你的计算机。
可见，安装此补丁失败的原因是，它又需要前置条件，原文摘录如下：

然后，KB2919355，又需要前置补丁KB2919442， 立即下载基于 x64 的 Windows Server 2012 R2 的KB2919442补丁 。

总之，注意安装补丁先后顺序。

解决办法之一：就是开启Windows自动更新，打全补丁，估计微软是为了告诉我们：他们不但修补了漏洞还增加了新功能。
