This page covers how to install and set up the Live Link Datastream plugin so you can begin streaming data from Shogun to the Unreal Engine 5.

## Prerequisites

To set up the Live Link plugin, complete the following steps:

1. Ensure you are using Windows 10.
2. Install the relevant version of Unreal Engine. These instructions apply to Unreal Engine 5 and later.
3. Download the Live Link plugin from [Vicon](https://www.vicon.com/software/third-party/unreal-engine/).

> ⚠️ **Important**  
> ⚠️ If you install an updated version of the Vicon Live Link plugin with the same version of Unreal Engine, remember to uninstall the current Live Link plugin first.

## Install the Live Link plugin

Before running the installer, ensure the downloaded engine version matches the Unreal Engine version. The version number is found in the installer filename.

1. To run the installer, double-click the MSI file.
2. Accept the license agreement and click **Next**. The installer should automatically detect the installed version of the engine.

> ⚠️ **Important**   
> ⚠️ If the installer did not detect the engine, click **Browse** and navigate to the installed engine location (by default this is *C:\Program Files\Epic Games\UE_5.x*), then click ** OK**.

## Disable the *.dll* filed used by LiveLink Hub - For Unreal engine 5.4 only

If you are using Unreal Engine 5.4, in order to use Live Link 1.9, you must disable the .dll file used by LiveLink Hub. To do this, rename the file.

1. Make sure the Unreal Engine program is closed.
2. Go to the Unreal Engine folder. This is found in `C:\Program Files\Epic Games\UE_5.4\Engine\Binaries\Win64\ViconDataStreamSDK_CPP.dll`
3. Find the file called `ViconDataStreamSDK_CPP.dll`
4. Rename this file `ViconDataStreamSDK_CPP_inactive.dll` or something equivalent.

> ⚠️ This step applies to Unreal Engine 5.4 only

3. In the **Plugins** window, scroll down to the **Mocap** section.
4. Ensure the **Vicon Datastream Live Link** plugin is enabled.
5. Restart the editor.
