Installation 为什么无法在Windows Server 2012 R2上安装AspNet5.ENU.RC1.exe？

在windows server 2012 R2实例（托管在azure中）上运行AspNet5.ENU.RC1.exe失败，出现0x80072f76-未指定错误

我了解到，从包含早期beta版vs web工具MSI文件的文件夹中安装可能会失败，并出现错误0x80091007-哈希值不正确，但这是一个不同的错误（我是从不同的文件夹安装的）。根据日志，这可能是网络问题。然而，从chrome上访问各种go.microsoft.com URL也可以。有什么好处

下面是日志文件片段的示例：

这是一个网络错误。默认情况下，Windows 2012 R2已启用IE增强安全配置。使用服务器管理器（或regedit）禁用IE增强安全配置（针对管理员和用户），然后再次运行exe。它会成功的。

在Windows 10上，我也有同样的错误。对我有帮助的是：

在Internet Explorer中单击菜单上的“工具”按钮，然后选择Internet选项。选择“高级”选项卡，一直到底部，您将看到“在安全和非安全模式之间切换时发出警告”选项取消选中该选项。

我按照danludwig的powershell链接和脚本禁用IE ESC。powershell脚本很好，因为它可以在安装完更新后轻松地重新启用ESC。
