Hey All. This seems pretty silly. Dropbox's standard installer is an "online" version that simply downloads a very small installer app that when opened, connects to dropbox's server and downloads and installs the full version automatically. This is nice and easy, unless you want to install dropbox on a number of Macs and prefer not to download it over and over again. Fortunately there is an "offline" installer containing the full version of the latest dropbox.
