Setting Up EL Launcher

This guide will walk you through the process of installing and configuring the EL Launcher, which allows you to stream your Unreal Engine applications directly from your own hardware.

After subscribing to the Pay Per License plan and downloading the EL package from the Control Panel, you can easily configure it on your machine and begin streaming your apps.

Prerequisites

Before installing, ensure the following:

1. Pay Per License Activation

Activate the Pay Per License plan plan from the Control Panel
purchase the number of Licenses needed.

2. Download Eagle Streaming Software (EL)

Download the EL zip file from the Control Panel into your C: Drive.

Note: Ensure your C: drive has sufficient free space.
All applications streamed through EL will be stored in:

C:\e3ds_streaming_apps

Required Space = zipped App size + extracted App size + largest extracted App size

4. Machine Requirements

Using EL

The machine where EL.exe is running acts as the streamer machine. You may stream apps from any client device using the streaming URL. Keep EL.exe running at all times.

Go to Control Panel

Select your app and play it

When you click Play App from your streamer machine, the system automatically creates a folder named C:\e3ds_streaming_apps on your local drive (if not avaialble it). This folder stores the applications downloaded from Eagle’s system for streaming.

When you play the app for the first time, it will enter the Acquiring Phase — downloading the app from Eagle’s system to your machine.
From the second run onward, the app will launch instantly.

If the App is running, then the setup was successful. If not, you will get errors. Please contact Support.

Notes

One running EL can serve only one user at a time. (1 CCU per License).

Please keep the terminal window open because closing it will stop the stream.

Don’t click inside the EL’s black window or any other window started by the stream. If clicked by mistake, just press the Esc button one time.

Tip : On Sleep mode, the Stream stops. You need to make sure the EL is running non stop. You can change it from your computer’s settings.
