Abstract: A database is built in a computer system and includes a characteristic set, an installation data set corresponding to the characteristic set, a reference command set and an execution set corresponding to the reference command set. A specified installation data in the installation set is used to automatically and continuously execute a series of installation commands of a PC game when a characteristic of the PC game matches a characteristic in the characteristic set corresponding to the specified installation data. Alternatively, a specified execution is performed when an installation command of the PC game matches a reference command in the reference command set corresponding to the specified execution. The computer system is thus capable of automatically installing thereinto a PC game from a storage medium.
