How To Uninstall Unity Completely

If you’re cleaning up disk space, resolving installation issues, or simply switching development environments, knowing how to uninstall Unity completely is essential. Whether you’re removing just one version or wiping out Unity and all its related files, this guide will walk you through each step safely and thoroughly.

Unity installations are often large and scattered across different folders. While uninstalling a Unity version might seem straightforward, leftover files, temporary caches, and package manager remnants can cause future conflicts or take up unnecessary space. In this post, we’ll explain how to remove Unity versions via Unity Hub, uninstall the Unity Hub itself, and fix stubborn uninstall issues that sometimes appear.

Why You Might Want to Uninstall Unity

Before we dive into the steps, here are a few reasons why you may want to uninstall Unity:

• You’re no longer using a specific version of the Unity Editor.

• You’re switching between Long Term Support (LTS) versions.

• Unity is taking up too much space.

• You want to perform a clean reinstall due to errors or corrupted files.

• You’re moving to a different game engine.

Whatever the reason, doing it correctly ensures you don’t leave behind conflicting or unnecessary files.

Unity Hub Uninstall Editor (The Easy Way)

If you’re using Unity Hub, the process to remove a specific version is simple. This is the recommended method because it ensures Unity-related folders are unregistered cleanly from the Hub.

Step-by-Step: Unity Hub Uninstall Editor

1. Open Unity Hub on your machine.

2. Go to the “Installs” tab from the left sidebar.

3. Locate the Unity version you want to uninstall.

4. Click the three dots (⋮) next to the version number.

5. Select “Uninstall” from the dropdown.

6. Confirm the uninstall when prompted.

Unity Hub will now begin removing the selected version. This includes the Unity Editor files, standard components, and associated build modules (like Android/iOS support).

Note: This method only removes the Unity Editor files—not Unity Hub itself or other versions installed.

How to Uninstall Unity Version Without Unity Hub

If Unity Hub is not installed or not working, you can still uninstall a specific version manually. Here’s how to uninstall Unity version directly from your file system.

On Windows

1. Press Windows + R and type:

   appwiz.cpl

   This opens the Programs and Features control panel.

2. Scroll down and find the Unity version you want to remove (e.g., Unity 2021.3.5f1).

3. Right-click and select Uninstall.

If Unity doesn’t appear in the list:

• Open File Explorer and go to:

  C:\Program Files\Unity\Hub\Editor\

• Find the version folder (e.g., 2021.3.5f1) and delete it manually.

Also, delete related folders (optional):

• Cache: C:\Users\[YourName]\AppData\Local\Unity

• Logs: C:\Users\[YourName]\AppData\LocalLow\Unity

• Project settings: Check your Unity project folders

On macOS

1. Open Finder, then go to the Applications folder.

2. Locate your Unity version directory or Unity Hub folder.

3. Drag the folder(s) to Trash.

4. Also delete:

   ~/Library/Application Support/Unity/
   ~/Library/Unity/
   ~/Library/Caches/com.unity3d.*

   Note: Use caution when deleting folders manually—avoid removing shared files unless you’re uninstalling all Unity software.

Remove these folders manually:
