Step-by-step: Enable .NET Framework 3.5
1. Open Windows Features
Click Start
Type: Windows Features
Click: “Turn Windows features on or off”

In the list, look for:
“.NET Framework 3.5 (includes .NET 2.0 and 3.0)”
👉 This is the key one
3. Enable it
If the box is unchecked → check it
If it’s a filled square (partially enabled) → click it until it becomes a full checkmark
Then click OK

This can take a few minutes
You may be prompted to restart → do it
