.NET Framework 4 多目标包无法卸载

Question

我目前正在尝试安装 Atmel Studio 6.2 with .NET，而安装的 Visual Studio 隔离 Shell 10.0 部分给我带来了一些麻烦。

当我尝试安装 Atmel Studio 时，它尝试安装 .NET Framework 4 并立即失败并显示生成的日志：

我的第一反应是尝试卸载/重新安装 .NET Framework 4。当我尝试卸载它时，收到以下错误：

找不到路径“C:\Users\MyUser\appdata\local\temp\sit31981.tmp\wcu\mtpack\NetFx_DTP.msi”。验证您是否有权访问此位置并重试，或尝试在可以安装产品 Microsoft .NET Framework 4 Multi-Targeting Pack 的文件夹中找到安装包“NetFx_DTP.msi”

我尝试在我的计算机上搜索以尝试找到此文件，但没有成功。我也做了一些研究，试图自己找到文件“NetFx_DTP.msi”，但也没有运气。

如果有人对如何解决此问题有任何提示，将不胜感激。谢谢！

Answer 1

对于 Windows 10 / Server 2012R2：

• 下载Windows 7.1 SDK ISO image
• 解压
• 运行Setup\MTPack\netfx_dtp.msi EXTUI=1

您现在应该有一个包含 4.0 内容的 %programfiles(x86)%\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\ 文件夹。
