@DeepaP17 Based on your screenshots…Postgres DB was not able to connect with port “5432”.
So while installing…you will see a screen with the port number for Tomcat & Postgres click on the "port availability" button to check the port open on your PC. if not change the port to 5433 for the Postgres DB.
