On a fresh installation of Windows Vista, we took screen shots when it came time to install Adobe's Flash plug-in into Internet Explorer for the first time. The sequence is especially interesting given Microsoft's emphasis on using Windows Vista as a non-administrative or "Lesser Privileged User" (LPU). Why? Because our first couple of attempt's failed. As it turns out, though, as best as we could tell, the failure had nothing to do with Vista, being an LPU, or Adobe's Flash. It has more to do the Web site that's calling for the Flash plug and how it responds when the Flash plug-in isn't there. In other words, depending on what site you go to, mileage may vary.
