ok Here we go my back up system crashed big time since I can't get into the computer to uninstall Hoster I am for sure I am going to lose this program on that comp and won't be able to reinstall on another computer for back up. The Mother Board is completely fried on this wonderful 6 month old Vista piece of crap. HP notebook. What I want to do is take and reinstall on my Dell desktop for emergancies. however can I do this without having to buy another full version of Hoster????
I never liked Vista in the First place my desktop has XP and The Laptop I use on a reg Basis is XP any help would be great thanks....
