Verify that you have the required hardware and software for Lumberyard. For more information, see System Requirements.

Using the Lumberyard Installer to Download Lumberyard

To install Lumberyard, download the LumberyardInstaller.exe. The Lumberyard Installer extracts the Lumberyard files and adds shortcuts on your desktop and in the start menu for the following:

  • Lumberyard Setup Assistant

  • Project Configurator

  • Lumberyard Editor

If your download is interrupted, the installer resumes the download automatically. By default, the Lumberyard Installer uses c:\Amazon as the root directory and the version number. You can specify a different directory; however, we recommend that you use the default.

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


If you encounter 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.
