Problems getting CF Administrator Page after Install of Developer Edition

Finished installing CF 11 Developer Edition and cannot connect to CF administrator and preinstalled Apache web server. I get this message:

Firefox can't establish a connection to the server at 127.0.0.1

Tried these URLs:

http://127.0.0.1/CFIDE/administrator/index.cfm

http://localhost/CFIDE/administrator/index.cfm

http://localhost:8500/CFIDE/administrator/index.cfm

Am able to get a web page that says "It works" when I try to access http://localhost

Does anybody have any advice?
