Getting demo setup

How do I get the demo to run? I have downloaded and extracted the demo files into C:\Users\Steve\Downloads\distribution-1.8.2-demo

When I enter http://localhost:8080/openhab.app?sitemap=demo in my browser URL I get:
This site can’t be reached

localhost refused to connect.
Search Google for localhost 8080 openhab
ERR_CONNECTION_REFUSED

I’m a total newbie here

http://www.openhab.org/getting-started/

Did you start openhab?

Yes, I was able to get it started once I got everything in the right
directories. Thanks!
