A software installing method for installing software to a computer includes searching printers that are installed in a network environment and displaying a list of found printers on a single searched printer screen. The found printers are listed in rows with each row comprising a checkbox and an identification name associated with the listed printers, and marking the checkbox in one of the rows and an operation for highlighting the identification name in the same row are independently acceptable. The method further includes displaying an image of at least one listed printer on the single searched printer screen whose identification name is highlighted on the single searched printer screen by a user and installing onto the computer the printer driver software that corresponds to the at least one listed printer where the checkbox associated with the printer is marked by the user.
