Watch out for the Demo Install

I'm amazed at how simple the demonstration install of NAV 2009 is. Click one button and it goes ahead and installs everything you need. A word of warning though, if you use this option and you have an existing NAV version installed (such as NAV 5.0 SP1) then the Microsoft Dynamics NAV folder will get overwritten without prompting. You may find it worthwhile copying your Microsoft Dynamics NAV folder to another folder (such as Microsoft Dynamics NAV 5.0 SP1) before doing the NAV 2009 install.
