Add-WindowsCapability 失败，并显示“找不到源文件”

我正在尝试在一些没有互联网连接的 Windows 10 系统上安装 RSAT。其中两个 Windows 10 系统是 20H2，其中一个是 21H2。这三个系统都有同样的问题。为了为离线系统安装 RSAT 工具，我找到了这个链接： https://michlstechblog.info/blog/windows-installing-rsat-tools-online-or-offline/

我使用此链接来确定在哪里/如何获取 FoD DVD ISO 文件： https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/features-on-demand-v2--capabilities?view=windows-11 也许问题的一部分在于 FoD DVD 来自 Windows 10 2004 版本，但我在 my.visualstudio 下载部分找不到更新的版本。我手动检查了 Windows 10 的其他版本（搜索“按需功能”没有找到任何内容）。

当我执行“get-windowscapability”时，它似乎正确读取了源代码：

 C:\WINDOWS\system32> Get-WindowsCapability -Name "RSAT*" -Online -LimitAccess -Source "E:\" | Foreach-object {write-host $_.Name}

但是当我尝试“add-windowscapability”时，它说找不到源文件：

我还检查了日志文件 (C:\Windows\Logs\DISM\dism.log)，那里显示了相同的错误。有什么办法可以让它正常工作吗？提前谢谢。
