Using the Lumberyard Installer

The Lumberyard Installer extracts the Lumberyard files and adds shortcuts to your desktop and start menu for the following:

  • Lumberyard Setup Assistant

  • Project Configurator

  • Lumberyard Editor

If you have an existing Lumberyard project and you want to upgrade, see Upgrading Lumberyard.


If you get file errors during extraction about AssetProcessor.exe, AssetProcessor_temp.exe, or CrySystem.dll, verify if your antivirus software is placing these files in quarantine. If needed, grant exceptions for the affected files.
