There is provided a system for refunding payment for software applied to a software distribution system comprising at least one user terminal and a center. The center notifys the user terminal of the deciphering information on condition that a user of the user terminal pays for the software which is supplied to the user terminal in a enciphered form. Then, the user terminal decipheres the enciphered software by using the deciphering information. The refunding system comprises an installation monitoring unit 38a that records whether the software is installed legally and normally. When the user requests the center to refund the paymenet for the software, a refund request unit 38b of the user terminal notifies the center of the installation history along with the refund request. The center determines whether the installation history contains a data indicating that the installing operation of the software is accomplished normally. The payment for the software is refunded to the user only when an installation accomplishment information is not contained in the installation history.
