Sorry for the late reply. You can always check the message again by looking into log file the rapidwiz produced. However a better way would be to try starting the services yourself and see which service is failing and then look into the log file of that particular services. This is exactly what rapidwiz is doing itself too.

Most common causes for these problems are:
1- Required linux packages are not installed. This results into apache service not starting.
2- The stage was corrupt (files were not downloaded properly or files were missing from stage).

Questions for you:
Did you install the two required packages?
Did you perform integrity test on your stage?

Next go into this video directly:

and try starting Oracle services from the linux prompt. See which service is not starting with status 0. We will then have to look into log file for that particular service to find out what is going on.
