Several older software compatible with XP are not with Vista; even when using install and run in compatibility mode for 98 or xp. examples of some of mine are Ulead PhotoImpact 11; Power DVD; Musicmatch; etc. Trying to install these then run either resulted in windows not allowing the install or killing the ap as it starts to load or ap causing blue/white screen. So you have to try the software to see; some may work some may not...part is software and part the configuration of the computer setup. Just my experience with Vista so far. take care, Magikil
