Abstract: A training support program which permits individual participants in a seminar to practice installing an application program and at the same time to actually install the program in existing network environments of the respective participants' corporations. A terminal device used by a participant in the seminar is caused to display, in accordance with the progress of the seminar, an input screen for entering environment information matching the environment of a network in which the participant intends to install the network application (Step S1). Subsequently, a computer acquires the environment information entered by the participant into the terminal device following the training procedure of the seminar, to generate, based on the acquired environment information, individual environment setting information necessary for configuring an operational environment for the network application on the network (Step S2).
