1. For installation of wall-paper press the Unpack button and pass into the catalog of unpacking.
2. Wall-paper is presented in the jpg format. Convert the necessary file in the bmp format (for what use any more or less serious graphic editor), copy in a directory of Windows and choose any file from the Properties Display/background menu.
But the most convenient way of installation is use of the Set Wallpaper function in a popular viewer of ACDSee or in the Internet Explorer browser.
