Been using it off and on via TAILS Linux, and find it does not slow downs things half as much as most claim. I'd like to get it installed on XP Pro, if possible. Tried the download from majorgeeks, which claimed it worked on XP, but after installation it said Win7 was required, so IObit Uninstaller to the rescue! I need to know which version is compatible with XP, and how to get it installed to the point its icon shows up on my desktop wallpaper. Anybody made it that far?
