Don't cancel the install, let it finish. If you just clicked the install icon from putting the disc in then all of your applications and everything will still be installed when it is finished.
You posted a similar thread last night in which you put in a cryptic title and then very poor descriptions of what you were trying to do.
Try to slow down and provide better descriptions of what you are trying to do. People here are very quick to help but they will stop responding to you if you can't take the time to frame your questions properly.
I also might recommend that since, as a new Mac user, you will have many many questions that you try to utilize the search features of this forum before asking 10000 questions the first week you have your Mac about how to do things that have been covered here already.
Good luck and enjoy the new Mac.
