Guide: How to Download & Install .NET Framework 3.5 Offline on Windows 10/11 (Free)

Why use the offline method?
Many older apps (games, accounting software, CAD tools) require .NET Framework 3.5. Installing it online via Windows Features often fails due to slow downloads or corporate restrictions. The offline method is faster and more reliable.

Steps:

1. From the mounted ISO, navigate to D:\sources\sxs.
2. Copy the entire sxs folder to a USB drive (e.g., E:\sxs).
3. On any target PC, run:

   DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:E:\sxs
   

Now you have a portable .NET 3.5 offline installer for all your Windows 10/11 machines. Guide: How to Download & Install
