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.

This is what happened when I followed #7:

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 stopping.
The Windows Update service was stopped successfully.

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 /Source:E:\sources\sxs /LimitAccess
'Dism' is not recognized as an internal or external command,
operable program or batch file.

C:\WINDOWS\system32>

I pasted the command with the last line replaced as instructed with the Drive letter changed to E where my usb stick is and as soon as I pasted I was very quickly looking at a CleanManager window which I checked all but one line to delete and hit Enter. I got the above message back immediately with no netfx3 installation being completed.

Now what?

Agh! not working for me either.
Dism /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:E:\sources\sxs /LimitAccess (where E is my dvd drive)
found this batch file (below), which seemed to work. got to 100% but then an 'Error 2'

@echo offTitle .NET Framework 3.5 Offline Installerfor %%I in (D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist "%%I:\\sources\install.wim" set setupdrv=%%Iif defined setupdrv (echo Found drive %setupdrv%echo Installing .NET Framework 3.5...Dism /online /enable-feature /featurename:NetFX3 /All /Source:%setupdrv%:\sources\sxs /LimitAccessecho.echo .NET Framework 3.5 should be installedecho.) else (echo No installation media found!echo Insert DVD or USB flash drive and run this file once again. echo.)pause

tried "Turn Windows features on or off". that failed too.

i have a stand alone copy of v3.5 - dotnetfx35setup.exe. It opens a dl and install window. it seems a file is being downloaded - according the the green progress bar, but then it says the feature couldnt be installed. Error Code: 0x80070002.

any ideas please?

Thanks.

I'm having this issue too, driving me crazy. I've tried the solution in post #7 with a windows install on my usb but I get the error:

Deployment Image Servicing and Management tool
Version: 10.0.17758.1

Image Version: 10.0.17758.1

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

Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Configure a Windows Repair Source | Microsoft Docs.

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

Any ideas?

I just spent 4 hours with microsoft on this and it's painful. Been ruining my work purchase for days.

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

This seemed to get me past the "looking for required files" part but now I'm stuck on "downloading required files"

Once it reaches 100% you can close the Window and carry on with what you were doing.
