The steps to install ILOG CPLEX involve identifying the correct distribution file for your particular platform, and then executing a command that uses that distribution file. The identification step is explained in the booklet that comes with the CD-ROM, or is provided with the FTP instructions for download. Once the correct distribution file is at hand, the installation proceeds as follows.

where path is the full path name pointing to the location of the ILOG CPLEX distribution file (either on the CD-ROM or on a disk where you performed the FTP download). On UNIX systems, both ILOG CPLEX and ILOG Concert Technology are installed when you execute the above command.
