我目前正在尝试安装Atmel Studio 6.2 with .NET，安装的Visual Studio Isolated Shell 10.0部分给了我一些麻烦。
当我尝试安装Atmel Studio时，它会尝试安装.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，或尝试在可从中安装产品的文件夹中找到安装包“NetFx_DTP.msi”Microsoft .NET Framework 4多目标包
我尝试在我的电脑周围搜索，试图找到这个文件而没有运气。我也做了一些研究，试图找到文件'NetFx_DTP.msi'本身也没有运气。
如果有人对如何解决这个问题有任何提示，我们将不胜感激。谢谢！

对于Windows 10 / Server 2012R2：
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。
