You must install your application server before you install the ATG platform. See your application server documentation for details.
Before you run the ATG setup program, make sure you have a supported JRE in place on your system, and that the JVM is in your system PATH. A sample J2EE application is deployed to your application server as part of the ATG platform installation process, so the JVM must be available to the installer. (Note: The stand-alone ATG Control Center includes its own JRE.)
For a detailed list of system requirements for the ATG platform, see the Supported Environments page on the ATG website (http://www.atg.com/en/products/requirements/).
