Why is .Net Framework 4.7.2 "not supported on this operating system"? (Windows 10)

I was trying to install the .NET 472 developer pack on a Windows 10 machine, and got this error.

enter image description here

I have been able to install this on other Win10 PCs, and also on Win7. So it doesn't make any obvious sense why it claims to be "not supported".

In the log there are some version checks:

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))

but that doesn't clearly indicate (to me) what I need to do to resolve the problem. Some Windows update is missing, perhaps?

Thanks

Microsoft has a support page which includes this error, but there is no pertinent resolution:

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]

This issue was apparently because my particular build of Windows 10 was quite old, and genuinely is not supported.

I was not able to 100% confirm this, because running the Windows 10 Updater failed multiple times on this PC (and so I gave up trying it) but several key things indicate this is the case:

  • Windows 10 build on the PC was 10240

  • But in the log the 472 installer wanted OSBuildNumber ≥ 14393

  • Different releases of Windows 10 have different levels of support by the framework. My particular install might have been an early or pre-release, because its version # (1701) is not listed at all on https://support.microsoft.com/en-ca/help/13853/windows-lifecycle-fact-sheet
