我最近在试着用Chocolatey通过Windows SDK 7.1安装mdbg.exe，是跟着网上的教程步骤来操作的，但碰到了个麻烦事儿。当我运行命令 choco install windows-sdk-7.1 -y 时，弹出了错误提示，说我必须安装“.NET Framework 4”才能继续。

下面是错误提示的截图：

错误提示的具体内容如下：

Windows SDK Setup
Some components cannot be installed

Some Windows SDK components require the RTM .NET Framework 4, Setup detected a pre-release version of the .NET Framework 4. If you continue with Setup, these components will not be installed. If you want to install these components, click Cancel, then install the .NET Framework 4 from the official designated download channel and then rerun Setup.

Click OK to continue.
