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.
