Issue: You skipped Web server installation when running EPM System Installer because you are using IIS as your Web server, but in EPM System Configurator there is no option for configuring the Web server.
Solution: Install Oracle HTTP Server, then restart EPM System Configurator.
You must install Oracle HTTP Server even if you do not want to use it as your Web server, because EPM System Configurator activates the Web server configuration task with the Oracle HTTP Server installation. When Oracle HTTP Server is installed, you can choose Oracle HTTP Server or IIS during Web server configuration.
