I just dual booted XP and Vista. I already had Vista installed but i am really tired of it so I installed a copied of XP. I want to use many of the programs in Vista but I get all of these errors because its not installed in the XP partition. I was wondering if there was a way to use Photoshop, Illustrator, Age of Empires III etc. on Xp without installing them on the vista partition and Xp partition.
