Enable the .NET Framework 3.5 by Offline or DISM on Windows 10, Windows 8.1, and Windows 8

Enable the .NET Framework 3.5 by Offline or DISM  on Windows 10, Windows 8.1, and Windows 8
  1. To start, you need a installation media of Windows 10. It can be the ISO you downloaded, a DVD, a USB, whatever you have.
  2. Insert your Windows 10 DVD or USB, or double click on it’s ISO file to mount it.Enable the .NET Framework 3.5 by Offline or DISM  on Windows 10, Windows 8.1, and Windows 8 01
  3. Open This PC and note what drive letter of the Windows 10 installation media.
  4. Now, open Command Prompt as Admin. (Press WindowsX to open the Start menu context menu. Now, press A to open the Windows Powershell (Admin).  Powershell
  5. Now just type in the following command:

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

Enable the .NET Framework 3.5 by Offline or DISM  on Windows 10, Windows 8.1, and Windows 8 04

Be sure to replace the X with the drive letter of your Installation media.

I replaced the X with G because the Windows 10 ISO file mounted automatically as G drive.

6. Now just press Enter and wait for the installation process to finish. Typically, the process will take a couple of minutes.

Here are the details of the command line parameters of the command given above:

/Online targets the current running operating system.

/Enable-Feature /FeatureName:NetFx3 specifies that .NET Framework 3.5 is to be installed/enabled.

/All enables all the parent features of the .NET Framework 3.5.

/LimitAccess prevents DISM from contacting Windows Update.

/Source specifies the location of the files needed.

Hope this helps and resolves your issue easily.
