# Quickstart Let's get started with the Spatial Reality Display app in Unreal Engine! ## Prerequisites :::caution If you are using Unreal Engine version **5.3** or later, an error will occur when you open a sample project. To solve this problem, you need to update the Plugin in the sample project to **5.3** or later. See **When the Spatial Reality Display plugin is placed in the project plugin search path** on the [Updating Unreal Engine](/Products/Developer-Spatial-Reality-display/en/develop/UnrealEngine/HowToUpdate/) page for instructions on how to update your plugin. ::: - Set up your Spatial Reality Display, if not, see: [Setup Spatial Reality Display](/Products/Developer-Spatial-Reality-display/en/develop/Setup/SetupSRDisplay.html), [Setup Spatial Reality Display Settings](/Products/Developer-Spatial-Reality-display/en/develop/Setup/SetupSRRuntime.html) - Connect your Spatial Reality Display to PC - Configure the settings of your Spatial Reality Display - Install Spatial Reality Display Settings - Installed Epic Games Launcher and Unreal Engine, see: [Installing Unreal Engine](https://docs.unrealengine.com/4.27/en-US/Basics/InstallingUnrealEngine/index.html) - Now we support **4.27, 5.4 and 5.5** :::note Only one Spatial Reality Display app can be run at a time. Additional apps will fail to launch. ::: ## Install Spatial Reality Display Plugin and Templates 1. Download latest **Spatial Reality Display Plugin** and **Spatial Reality Display Templates** from [Download Page](/Products/Developer-Spatial-Reality-display/en/develop/Setup/DownloadInfo.html). 2. Install Spatial Reality Display Plugin. Unzip **srd-ue-plugin-4.XX-x.y.z.nnnnn.zip** and copy extracted folder SRDisplayPlugin into one of the search paths for Plugins, either in your project or in the Engine itself. See [here](https://docs.unrealengine.com/en-US/Programming/Plugins/index.html) for instructions on installing Plugins. For simplicity of explanation, we assume you have copied SRDisplayPlugin into **C:\Program Files\Epic Games\UE_x.xx\Engine\Plugins\Marketplace\\**. (If there is no Marketplace folder, create one.) 3. Install Spatial Reality Display Templates. Unzip **srdisplay-ue-templates-x.y.z.nnnnn.zip** and copy extracted folders TP_SRDisplay and TP_SRDisplayBP into the Engine's Templates directory. See [here](https://docs.unrealengine.com/en-US/Engine/Basics/Projects/CreatingTemplates/index.html) for instructions on installing Templates. For simplicity of explanation, we assume you have copied TP_SRDisplay and TP_SRDisplayBP into **C:\Program Files\Epic Games\UE_x.xx\Templates\\**. ## Build and run the Spatial Reality Display app 1. Download Unreal Engine Samples Project of Spatial Reality Display from [Download Page](/Products/Developer-Spatial-Reality-display/en/develop/Setup/DownloadInfo.html#unreal-engine-samples). 2. Unzip **SRDisplaySamplesProject_x.y.z.nnnnn.zip** into your any folder. 3. Open the samples with your UE Editor. Right click SRDisplaySamples.uproject and select "Switch Unreal Engine version..." from context menu. A dialog window called "Select Unreal Engine Version" will open.
