The installation method and file you need depends on your user account permissions.
To install in a UNIX host, or as non-root in a Linux host, download the appropriate tar.gz file for your environment from the Platform FTP site.
To install as root in a Linux host, download the appropriate .rpm file for your environment.
Linux root users can install using either the tar.gz or .rpm installation files.
