Database cannot connect to 'localhost'

Database cannot connect to 'localhost'

I am using ZENON 7.20 demo mode. But there is a problem connecting the database. When I start the program, Output message show me the message that "Database cannot connect to 'localhost'". And when I import project program showed me a message that "Service 'zenAdminSrv' on server 'localhost' is not running!".
How can I fix this problem? Additionally I started zenAdminSrv to run from Services (services.msc), Zenon web server started from the control panel, also I checked Internet Information Services (IIS) from Windows Features.
