问 为什么.Net框架4.7.2“在这个操作系统上不受支持”？(视窗10)

EN

我试图在Windows10机器上安装.NET 472开发人员包，但得到了这个错误。

​

​

我已经能够安装在其他Win10 PC上，也可以在Win7上。因此，它声称“不受支持”是没有任何明显意义的。

在日志中有一些版本检查：

将包条件计算为false： ((VersionNT = v6.1和ServicePackLevel >= 1) OR (VersionNT = v6.2和NOT (OSInstallationType = "Client"))或(VersionNT = v6.3)或 (VersionNT = v10.0和OSBuildNumber >= 14393) OR (VersionNT > v10.0))

但这并不能清楚地说明我需要做些什么来解决这个问题。是不是缺少了一些Windows更新程序？

谢谢

微软有包含此错误的 支持页面 ，但没有相关的解决方案：

此操作系统不支持.NET框架4.5*.x*/4.6*.x*/4.7*.x*： 对于Windows7上的.NET框架安装失败.所有特定于Win7 / nothing用于Win10
