Method of installing application programs and computer accessible recording medium storing installation program

A non-transitory computer-readable storage medium containing an installation program which, when executed by a computer, realizes a method of installing an application program to an information processing device which is connected with an information processing server via a network using setting information including at least one setting item, the method comprising the steps of:

• determining whether to execute a normal installation or a reference installation based on whether a user registration has been performed and the setting information has been stored in the information processing server;
• if it is determined to execute the normal installation,
• transmitting a request for a user who installs the application program to input the setting information,
• receiving the setting information input by the user in response to the request for the user who installs the application program to input the setting information,
• executing the normal installation using the setting information input by the user, and
• transmitting the setting information to the information processing server to store the setting information in the information processing server;
• and
• if it is determined to execute the reference installation,
• acquiring the setting information from the information processing server,
• displaying the acquired setting information on a display unit,
• transmitting a request for the user to select whether the setting information acquired from the information processing server is to be changed,
• receiving the user selection in response to the request for the user to select whether the setting information acquired from the information processing server is to be changed,
• transmitting a request for the user to input the change for each setting item if the user selection indicates that the setting information acquired from the information processing server is to be changed,
• receiving the change input by the user in response to the request for the user to input the change for each setting item,
• executing the reference installation using the setting information which reflects the change input by the user in a case that the change has been input by the user, and
• executing the reference installation using the setting information acquired from the information processing server in a case that no change has been input by the user.
