Alright so, I'm trying to install an app. that is supported by either XP, Vista, or Mac. Now I'm trying to go for the XP, so can a 2010 Sony Vaio e series be turned into an XP? Since the message that comes up all the time when attempting to install this app. it says I need a different version of some thing, but I don't know what, since it only says I should try to install it when I get a different version of some thing. What can be done to make it accept this app. supported by XP?
