Did you try installing New Vegas in offline mode? No didn`t think so, offline mode means no possible way to install New Vegas.
Got a laugh from your picture at least;)
Oh I'm sorry, I assume that every complainer here has the CD for the game to install the game and further are just being stupid about the game needing an internet connection to be played. If you have the internet connection to download it just
download it and go offline or somethng! Here's a scenario for you! If your playing Fallout New Vegas and the modem dies or something
you can still play the game. Why? Because Steam has gone and said "Well you logged onto this computer using this account and this game is authenticated so play it whenever you feel like it"
Did I try installing Fallout: New Vegas in Offline mode, Of course not! How stupid do I have to be to go and say "Well I can get my game off the internet without being on the internet because magical space beams are giving me the game." Furthermore I pre-ordered and pre-installed this game before release.
And further more, upon further inspection of what you type, YOU HAVE A CD! JUST GO THROUGH INSTALLING IT WITH THE FREAKING CD! If Steam is telling you that you have to wait till tomorrow then more then likely Steam is having a server issue and you might have to hit that lovely HELP->Steam Support and see where that gets ya.
Now then let's get down to procedure on how Steam works from a retail buyers side:
You buy your physical copy of FO:NV and install it. You should more than likely be told to install Steam or something. Do that, make an account and proceed to installing the game. In another scenario you will more than likely install Steam, make account, and activate New Vegas over Steam making Steam register that you bought the game and now it is automatically installing New Vegas for ya. If you don't want it to download go right click New Vegas in Steam and click "Delete Local Content" and then go on with your CD installation. After the CD install (Or WHATEVER INSTALL YOU DECIDED TO GO WITH) is done Steam will now install the most recent patch for you and you should be ready to go.
If this did not help you then proceed to look for your nearest search engine and ask it for help for anything related to Steam because more than likely someone else had the same problems as you at some point in time.
