#### Download Unreal Engine

1. [Download](https://www.unrealengine.com/download) the Epic Games Launcher. While the Unreal Engine is open source and free to download, registration is still required.
2. Run the Epic Games Launcher, open the `Library` tab on the left pane.
Click on the `Add Versions` which should show the option to download **Unreal 4.27** as shown below. If you have multiple versions of Unreal installed then **make sure 4.27 is set to `current`** by clicking down arrow next to the Launch button for the version.
2. Run the Epic Games Launcher, open the `Unreal Engine` tab on the left pane, then the `Library` tab on the top.
Click on `Install a new version of the Unreal Engine` (Next to `Engine Versions`) which should show the option to download **Unreal 4.27** as shown below. If you have multiple versions of Unreal installed then **make sure 4.27 is set to `current`** by clicking down arrow next to the Launch button for the version.

**Note**: AirSim also works with UE >= 4.24, however, we recommend 4.27.
**Note**: If you have UE 4.16 or older projects, please see the [upgrade guide](unreal_upgrade.md) to upgrade your projects.
