The command listed in the CA Harvest Software Change Manager Implementation Guide to install CAPKI on page 85 is
setup install caller=CallerID options
On the RedHat Linux platform this is incorrect. If you use this command you will not get the CAPKI installation program but instead the RedHat system setup menu:
If you get this menu, use your <Tab> key to navigate to the "Quit" button and press the <Enter> key. This should return you to the console.
To install CAPKI on a RedHat Linux platform you should use this command instead:
./setup install caller=CallerID options
