For more information about how to activate Unity manually, refer to the Unity Manual Activation Guide.

Activate a license on the offline computer

Follow the manual activation instructions to activate your license on an offline computer.

Install Unity Hub offline

1. As a part of the downloaded files from the Unity Download Assistant is a file “UnityHubSetup.exe”. Run this file on the offline machine to install Unity Hub. Unity Hub assists in managing your Unity Projects and Editor Installations.

2. To locate the existing Unity installation, navigate to the “Unity.exe” installed previously. For example:

   C:\Program Files\Unity XXXXXX\Editor\Unity.exe (Default Unity install path without the Hub)

   or

   C:\Program Files\Unity\Hub\Editor\20XXXX\Editor\Unity.exe (Default Unity install path with the Hub)

3. To deactivate the Welcome screen:

If you’ve never set up a services-config.json file before, you need to create both the config directory and the services-config.json file:

• MacOS: /Library/Application Support/Unity/config
• Windows: C:\ProgramData\Unity\config
• Linux: /usr/share/unity3d/config

Inside this file, add the following option:

{
  "hubDisableWelcomeScreen": true
}
