为什么.Net Framework 4.7.2“在此操作系统上不支持"?(Windows 10) [英] Why is .Net Framework 4.7.2 "not supported on this operating system"? (Windows 10)
问题描述
我试图在Windows 10计算机上安装.NET 472开发人员包，但出现此错误.
I was trying to install the .NET 472 developer pack on a Windows 10 machine, and got this error.
我已经能够在其他Win10 PC以及Win7上安装它.因此，为什么声称不受支持"并没有任何明显的意义.
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".
日志中有一些版本检查:
In the log there are some version checks:
捆绑条件评估为false:
Bundle condition evaluated to false:
((VersionNT = v6.1 ANDServicePackLevel> = 1)或(VersionNT = v6.2 AND NOT(OSInstallationType ="Client"))或(VersionNT = v6.3)或
(VersionNT = v10.0 AND OSBuildNumber> = 14393)或(VersionNT>v10.0))
((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))
但这并不能向我明确表明解决该问题所需要做的事情.也许缺少某些Windows更新?
but that doesn't clearly indicate (to me) what I need to do to resolve the problem. Some Windows update is missing, perhaps?
谢谢
Microsoft具有支持页面，其中包含此错误，但没有相关的解决方法:
Microsoft has a support page which includes this error, but there is no pertinent resolution:
此操作系统不支持.NET Framework 4.5 * .x */4.6 * .x */4.7 * .x *:
The .NET Framework 4.5*.x*/4.6*.x*/4.7*.x* is not supported on this operating system:

推荐答案
此问题显然是因为我的Windows 10特定内部版本很旧，并且确实不支持.
我无法100％确认这一点，因为运行 Windows 10 Updater 在此PC上多次失败(因此我放弃尝试了)，但是有几项关键提示表明是这种情况:
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:
-
在PC上构建的Windows 10为 10240
但是在日志中，472安装程序希望OSBuildNumber≥ 14393
But in the log the 472 installer wanted OSBuildNumber ≥ 14393
Windows 10的不同发行版对框架的支持程度不同.我的特定安装可能是早期或预发行版本，因为
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
