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...

Hi,

You may need to change the D: in "Source:D:" to the drive your installation media is on...

The installation media needs to be the same version as the OS, or possibly a newer build.. I don't know if an older build will work..

Some of the features on the installation media have the Build number as part of the file name, and if it is not the same as the OS in use, it may not be recognized...

I will see if I can clarify that when I get the chance...

Hi,

Just wanted to let you know that I tried both an older version of Windows 10 as well as a newer version... Both worked...

I did have a problem copy\pasting the command in the reply marked as answer... It was not copying properly for some reason...

I used the one in your reply, and it worked...

I got this at CMD:

DISM doesn't recognize the command-line option ":\sources\sxs".

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

.NET Framework 3.5 should be installed
