.net - 为什么“此操作系统不支持 .Net Framework 4.7.2”？（视窗 10）

问题描述

我试图在 Windows 10 机器上安装 .NET 472 开发人员包，并收到此错误。

在此处输入图像描述

我已经能够在其他 Win10 PC 和 Win7 上安装它。因此，为什么它声称“不受支持”并没有任何明显的意义。

在日志中有一些版本检查：

捆绑条件评估为假：

((VersionNT = v6.1 AND ServicePackLevel >= 1) OR (VersionNT = v6.2 AND NOT (OSInstallationType = "Client")) OR (VersionNT = v6.3) OR
(VersionNT = v10.0 AND OSBuildNumber >= 14393 ) 或 (版本NT > v10.0))

但这并没有清楚地表明（对我而言）我需要做什么来解决问题。可能缺少某些 Windows 更新？

谢谢

Microsoft 有一个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 Framework 4.5*.x*/4.6*.x*/4.7*.x*：

对于 Windows 7 上的 .NET Framework 安装失败... [所有特定于 Win7 / Win10 没有]

仅供参考，整个日志文件包含：

解决方案

这个问题显然是因为我的特定版本的 Windows 10 非常旧，并且真正不受支持。

我无法 100% 确认这一点，因为在这台 PC 上运行Windows 10 更新程序多次失败（因此我放弃了尝试），但有几个关键事项表明情况确实如此：
