GOOD NEWS!

The new launcher (still in beta/preview but fully functional) is compatible again with old CPUs which do not support SSE4.2.

You can download it here:

> **[Epic Games Launcher](https://launcher.epicgames.com/)**
>
> The new Epic Games Launcher: faster from the first click, built around your games.

On system requirements for Windows it says:

| CPU | Intel Core i3 / AMD Ryzen 3 |
| --- | --- |

But that is false. Works perfectly well on a Core 2 Duo. So now you can use an official launcher again if you don’t want to use Heroic or an old version of EGS launcher.
