Question

Whenever I try to install .NET Framework 3.5, I get this error:

0x800F0922 CBS_E_INSTALLERS_FAILED: Processing advanced installers and generic commands failed.

When running command:

cmd /k Dism.exe /Online /Enable-Feature /FeatureName:NetFX3

It returns:

Deployment Image Servicing and Management tool

Image Version: 10.0.19045.2846

Enabling feature(s)
[==========================100.0%==========================]

Error: 0x800f0922

DISM failed. No operation was performed.
For more information, review the log file.

The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

I have also tried the GUI install, but it also failed.

How do you help me?

Answer 1

Please try installing NetFx3 from the Windows 10 ISO.

Download the Windows 10 ISO using MCT or Rufus.

Mount the ISO by right-clicking on the ISO and choosing "Mount".

The ISO will be assigned a drive letter -- e.g., H:\

Run the following DISM commands mentioning the source (H:\Sources\SxS) folder.

dism /online /Add-Package /PackagePath:H:\Sources\SxS\microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab

And then run:

dism /online /enable-feature /featurename:NetFX3 /Source:H:\sources\sxs /LimitAccess

Please upload your CBS logs.

1. Open the folder "C:\Windows\Logs\CBS"
2. Select all files, right-click on the selection, and click Send to → Compressed (zipped) folder.
3. Click Yes when you see the following prompt:

Windows cannot create the Compressed (zipped) Folder here.

Do you want it to be placed on the desktop instead?

4. Upload the zip file to your OneDrive/Dropbox and share the link here.
