I am getting a problem at the installation process of this software like clsRCDCInfo:CreateRCDCDatabase - No connection could be made because the target machine actively refused it 127.0.0.1:5433. What it means? How can I solve this?
That message indicates that you can't connect to the local PostgreSQL database because of various reasons like service not running, bad password, file corruption, etc.
I advise restarting or starting the database service using the commands posted on the Documentation page: http://www.postgresql.org/docs/9.1/static/app-pg-ctl.html
After the service is running, try connecting again and it should work.
