My installation too is this way.
I would be interested in finding a solution as well.

Enter "Port 80 in use by "Unable to open process" with PID 4!" into Google

seems you all have the same problem with me. port 80 is using by another system
try to change the port , you may look many video on youtube that can helps you to make the apache running !! good luck

The recommend way is not to change Apaches port but stop the application which is using this port if it is not needed.
