Technical Brief: Offline Installation of .NET Framework 3.5 on Windows 10 (64-bit)

Prepared for: System Administrators and Advanced Users
Date: Current
Subject: Sourcing and deploying .NET Framework 3.5 (includes 2.0 & 3.0) without an internet connection.

Method B: Offline Deployment via Windows Installation Media (Most Reliable)

The safest way to get a 100% offline installer is to extract it from your Windows 10 installation ISO or USB drive.

What you need: A Windows 10 64-bit installation USB or ISO file (the same version as your PC).

Steps to extract the offline installer:

Mount the Windows 10 ISO (right-click the ISO file → Mount). It will appear as a new drive (e.g., D:\).
Open Command Prompt as Administrator.
Run this command to create a local source:
```
Dism /online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs
```
(Replace D: with the drive letter of your mounted ISO)
Windows will install .NET 3.5 directly from the ISO without internet.

To save the installer files for future offline use:

Copy the entire D:\sources\sxs folder to your hard drive (e.g., C:\Net35_Offline). You can use this folder on any Windows 10 64-bit PC.

Step 3: Verify the Installation

After installation, confirm everything works.

Press Win + R, type regedit and hit Enter.
Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5
Check the Version and Install DWORD value (should be 1).

Or simpler:

Open Control Panel → Programs → Turn Windows features on or off.
Ensure .NET Framework 3.5 has a filled (not empty) checkbox.
