.net - 为什么 .Net Framework 4.7.2 "not supported on this operating system"？ (Windows 10)

Question

我试图在 Windows 10 机器上安装 .NET 472 开发人员包，但出现此错误。



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”没有任何明显的意义。

在日志中有一些版本检查:

Bundle condition evaluated to false:

((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) OR (VersionNT > v10.0))

但这并没有清楚地表明(对我来说)我需要做什么来解决这个问题。也许缺少某些 Windows 更新？

谢谢

微软有 a support page其中包括此错误，但没有相关的解决方案:

The .NET Framework 4.5*.x*/4.6*.x*/4.7*.x* is not supported on this operating system:

For failed installations of the .NET Framework on Windows 7 ... [all specific to Win7 / nothing for Win10]

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

我无法 100% 确认这一点，因为正在运行 the Windows 10 Updater在这台 PC 上失败了多次(所以我放弃了尝试)但有几个关键的事情表明情况确实如此:

PC 上的 Windows 10 版本是 10240

但是在日志中 472 安装程序想要 OSBuildNumber ≥ 14393

不同版本的 Windows 10 具有不同级别的框架支持。我的特定安装可能是早期版本或预发布版本，因为它的版本号 (1701) 根本没有在 https://support.microsoft.com/en-ca/help/13853/windows-lifecycle-fact-sheet 上列出。
