Open Notepad then copy in this code

@echo off

Title .NET Framework 3.5 Offline Installer

for %%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=%%I

if defined setupdrv (

echo Found drive %setupdrv%

echo Installing .NET Framework 3.5...

Dism /online /enable-feature /featurename:NetFX3 /All /Source:%setupdrv%:\sources\sxs /LimitAccess

echo.

echo .NET Framework 3.5 should be installed

echo.

) else (

echo No installation media found!

echo Insert DVD or USB flash drive and run this file once again.

echo.

)

pause

Save the file as netfx.cmd

Right click it and choose Run as administrator.

The file will install .NET Framework 3.5 automatically after finding the drive letter of your Windows 10 installation media.

If media not found insert Win10 Usb or Dvd drive and run as administrator again.

Hi,

This worked for me... You need to put Installation Media in your DVD drive, Flash Drive or elsewhere... I used a Flash Drive...

Enter this into Command Prompt (Admin) or PowerShell (Admin)…

Dism /online /enable-

feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess

Change D: to drive letter the installation media is on...

    I have the same error code when downloading the .net framework 3.5 and I have copy the above code from

    @echo off

    Title .NET Framework 3.5 Offline Installer

    for %%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=%%I

    if defined setupdrv (

    echo Found drive %setupdrv%

    echo Installing .NET Framework 3.5...

    Dism /online /enable-feature /featurename:NetFX3 /All /Source:%setupdrv%:\sources\sxs /LimitAccess

    echo.

    echo .NET Framework 3.5 should be installed

    echo.

    ) else (

    echo No installation media found!

    echo Insert DVD or USB flash drive and run this file once again.

    echo.

    )

    pause

    then save it as netfx.cmd

    I ran it as administrator but it did not work, is there anything I had done wrong?

    For this:-

    .NET Framework 3.5 installation error: 0x800F0950

    1. You have to insert the Windows 10 bootable CD or DVD or USB Disk.
    2. Open that Windows 10 bootable drive and then open "sources" folder and then now you see the "sxs" folder and copy that folder and then paste the folder in the main "C drive directory".
    3. Open the CMD with Open as Administrator.
    4. Type this "dism /online /enable-feature /featurename:netfx3 /all /source:c:\sxs /limitaccess"and press Enter ;; Wait till operation not completed it takes almost 2 min.
    5. Now Go to Control Panel and go to Turn Windows Features on or off.
    6. Tick the .NET Framework 3.5 (includes 3.0 and 2.0) and now Press ok and restart you PC.

    Enjoy.....
