These screensavers are exe. files and will install automatically. However, all of you Windows XP users will have to do a bit of moving once the file installs. The Screensaver will install itself to the main "Windows" folder. Locate the screensavers icon and move it into the "system32" folder. From there, simply add a lowercase ss to the front of the screensavers name. This will make it available with all of your other screensavers in the "Control Panel".
