It pops a modal dialog saying that if you cancel the software won't get to be installed. I don't have a screenshot handy, but I get the feeling it was worded a bit verbosely to prevent people from guessing the correct of the two buttons to actually stop the install. If you pick the right button, your default browser gets force-directed to a page on their site to either a) re-start the download and install process or b) send a message to their CS team so that they can assist you with installing it. (I've got to admit, that is crafty, since you can presumably do the entire thing automatically.)
