我尝试在 Windows 8 上安装 .NET 3.5，但一直出现错误 0x800f0922。根据我在 answers.microsoft.com 上看到的信息以及堆栈溢出我认为修复此问题最简单的方法是执行系统刷新，但这会删除我从光盘安装的所有软件。我刚刚搬家，所以我不想这么做，因为我不知道很多软件的所有安装介质实际上在哪里，所以如果可能的话，我更愿意找出问题实际发生的位置。（此外，我安装了很多软件。重新安装所有软件需要很长时间，不幸的是我没有时间。）
按需错误屏幕将我发送到KB2734782，这没什么帮助。
当我从 StackOverflow 帖子运行此 DISM 行时：
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess
我在终端上得到以下输出：

有人知道导致安装失败的真正原因吗？如果知道，我该如何修复？请不要只说“刷新操作系统”。:)
答案1
您的源参数错误。文件已从 C:\Windows\WinSxS 中删除。您必须指向已安装的 ISO/DVDdrive/USB 拇指驱动器上的 SxS 文件夹：
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:DRIVELETTER:\sources\SxS /LimitAccess
在 Windows 8 上安装 .NET Framework 3.5
答案2
我可以确认如下行为。
在使用 WSUS 的域中，通过控制面板添加功能“.NET Framework 3.5（包括 .NET 2.0 和 3.0）”失败。
以管理员身份针对原始安装介质运行以下命令也会失败安装语言包时，在我的情况下是在德语安装中使用英语。
Dism /online /enable-feature /featurename:NetFx3 /All /Source:x:\sources\sxs /LimitAccess
这里的错误和楼主提到的一样。“未找到源”通常在 65% 左右。
另外，仅仅切换回原始语言是不够的。必须卸载已安装的语言包并重新启动系统。
此后上述命令成功运行。
答案3
请尝试以下操作：
使用具有管理员权限的命令提示符，然后输入：
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren c:\windows\SoftwareDistribution sd1.old
ren c:\windows\system32\catroot2 catroot.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
完成此操作后，尝试重新安装。
