Whether you’re a beginner or a seasoned developer, Unity provides a scalable platform that grows with your skills.

How To Install Unity Editor

To build anything with Unity, you first need to install the Unity Editor — the development environment where you’ll create and test your projects.

Step 1: Download Unity Hub

Unity Hub is the official application management tool used to install and manage multiple Unity Editor versions.

  1. Go to the official Unity download page:
    https://unity.com/download

  2. Download and install Unity Hub for your operating system (Windows/macOS).

  3. Once installed, sign in with your Unity ID or create one if you don’t have an account yet.

Tip: You must be signed in to install and launch Unity versions and projects.

Step 2: Add a Unity Editor Version

Now that you have Unity Hub:

  1. Open Unity Hub and go to the Installs tab.

  2. Click “Install Editor” or the Add button.

  3. Select the latest LTS (Long-Term Support) version, which is recommended for stability.

  4. Click Next.

This is the core step in understanding how to install Unity Editor — picking the version that suits your development needs.

Step 3: Choose Build Support Modules

During installation, Unity gives you the option to add platform-specific build modules. These modules are critical for deploying your project to various devices, such as Android, Windows, iOS, and WebGL. When learning how to install Unity game engine, it’s essential to select the correct build support modules based on the platforms you intend to target.

We recommend selecting the following modules:

  • Windows Build Support (Mono/IL2CPP)

  • Android Build Support

  • WebGL (if you plan to publish to the web)

These options allow you to develop and export games for Android, Windows, and other platforms.

Step 4: Install the Editor

After selecting modules:

  1. Click Install.

  2. Unity Hub will download and install all required files.

  3. Wait for the process to complete — this may take several minutes depending on your internet speed and selected modules.

Once installed, Unity Editor will appear in the Installs tab of Unity Hub, ready for use.

Step 5: Create Your First Project

Now that Unity Editor is installed:

  1. Go to the Projects tab in Unity Hub.

  2. Click New Project.

  3. Choose a template: 2D, 3D, URP (Universal Render Pipeline), etc.

  4. Set a name and location for your project.

  5. Make sure your newly installed Unity version is selected.

  6. Click Create.

Your first Unity project will launch, and you’re now officially ready to start building.
