An operating system account you use to install Content Platform Engine.
If you are upgrading on the same machine where Content Platform Engine (or Content Engine) was previously installed, use the same installer account that you originally used to install that software. The installation program requires this to detect that it is an upgrade and to use the same installation path.
If you are upgrading on a new machine, where Content Platform Engine has never been installed, create the cpe_install_user as explained here.
If your operating system is AIX®, HPUX, HPUXi, Linux, Linux on System z®, or Solaris and you do not know the account that was used to install Content Platform Engine (or Content Engine), skip this procedure and see the procedure Assigning directory permissions to a new installer account on AIX, HPUX, HPUXi, Linux, Linux on System z, or Solaris.
