Install the latest version of EC2Config

By default, the EC2Config service is included in AMIs prior to Windows Server 2016. When the EC2Config service is updated, new Windows AMIs from Amazon include the latest version of the service. However, you need to update your own Windows AMIs and instances with the latest version of EC2Config.

Note

EC2Launch replaces EC2Config on Windows Server 2016 and 2019. For more information, see Configure a Windows instance using EC2Launch. The latest launch service for all supported Windows Server versions is EC2Launch v2, which replaces both EC2Config and EC2Launch.

For information about how to receive notifications for EC2Config updates, see Subscribe to EC2Config service notifications. For information about the changes in each version, see the EC2Config version history.

Before you begin

  • Verify that you have .NET framework 3.5 SP1 or greater.

  • By default, Setup replaces your settings files with default settings files during installation and restarts the EC2Config service when the installation is completed. If you changed EC2Config service settings, copy the config.xml file from the %Program Files%\Amazon\Ec2ConfigService\Settings directory. After you update the EC2Config service, you can restore this file to retain your configuration changes.

  • Note

    If your version of EC2Config is earlier than version 2.1.19 and you are installing version 2.3.313 or later, you can install it directly without installing version 2.1.19 first.
