Take a look at .NET Framework 3.5-Installationsfehler: 0x800F0906, 0x800F081F, 0x800F0907 :
I prefer the method 3: Use Windows installation media.
You can use the Windows installation media as the file source when you enable the .NET Framework 3.5 feature. To do this, follow these steps:
- Insert the Windows installation media.
- At an elevated command prompt, run the following command:
Dism /online /enable-feature /featurename:NetFx3 /All
/Source:<drive>:
\sources\sxs /LimitAccess
- Note In this command, is a placeholder for the drive letter for the DVD drive or for the Windows installation media. For example, you run the following command:
Dism /online /enable-feature /featurename:NetFx3 /All
/Source:D:\sources\sxs /LimitAccess
dism.exe /online /cleanup-image /scanhealth
anddism.exe /online /cleanup-image /restorehealth
as per the same page? I don't think that the error code changed in Win10.
