Abstract

The method and system for limiting the number of installations of a computer software program located on a read only disk from the read only disk to a computer. The read only disk is linked to a removable read/write memory by data on the removable read/write memory corresponding to data on the read only disk. Prior to installation of the computer software program from the read only disk to the computer, software residing on the removable read/write memory determines whether the installation is authorized. Such determination is made by comparing identification information corresponding to computers on to which the computer software program has previously been installed to installation limitations dictated by a software license agreement.
