    Go to Start/Search and type appwiz.cpl and press enter. Click on Turn Windows Features On or Off. Put a check box in .Net Framework 3.5

    When I do this I get a progress bar that just gets stuck, same as the GUI version does.

    If you are running into the same problem, here is another solution. It requires you to have a Windows 10 installation USB stick (DVD might work as well). Plug it it and run the command posted by TairikuOkami, but replace the last line with:
    Code:
    ​Dism /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
    where D: is the drive letter of the Windows 10 installation USB stick/DVD.

    This command will install NetFx3 from the local file on the USB stick/DVD (microsoft-windows-netfx3-ondemand-package.cab) instead of attempting to download it and getting stuck.

    Tairiku,

    I am having a similar problem activating .net Framework 3.5 as a result of my Source files missing. I was hoping by using your command above i might have an easier time repairing this than i have had with Microsoft's suggestion but when I ran it nothing changed and this is what happened in the elevated command window:

    Microsoft Windows [Version 10.0.17040.1000]
    (c) 2017 Microsoft Corporation. All rights reserved.

    C:\Windows\system32>taskkill /im TiWorker.exe /f
    ERROR: The process "TiWorker.exe" not found.

    C:\Windows\system32>net stop wuauserv /y
    The Windows Update service is not started.

    More help is available by typing NET HELPMSG 3521.


    C:\Windows\system32>rmdir "%systemroot%\SoftwareDistribution\Download" /s /q

    C:\Windows\system32>del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat" /s /f /q
    Could Not Find C:\ProgramData\Application Data\Microsoft\Network\Downloader\qmgr*.dat

    C:\Windows\system32>cleanmgr /sageset:65535 & cleanmgr /sagerun:65535

    C:\Windows\system32>​Dism /Online /Enable-Feature /FeatureName:NetFx3 /All
    '​Dism' is not recognized as an internal or external command,
    operable program or batch file.

    C:\Windows\system32>


    I really could use some thorough guidance with using DISM to correct this problem. I don't even understand where the Sources file exists in order to verify it is missing!

    I do have the Insiders build 17040 that I am currently running made into a bootable installation usb stick that I created with UUP2ISO but I no longer have the ISO that was created. Can this be used in place of the Windows Installation disk that is required to be pointed to in the DISM command?

    Please let me know when you can...

    Thanks,

    Daniel R

    cereberus,

    This looks like the suggestion I read on Microsoft.com although the process seems much less daunting posted the way it is here as opposed to how it was posted there. Hmmm.

    I will try this and post my result later today.

    Thanks!
