Though all the permission listed in below document followed, the install still failed

1. Ensure that the non-root user account has read, write, and execute (rwx) access to the following directories and their files:
   • .profile file in your home directory (write and execute permission)
   • opt/bmc
   • /tmp
   • JREHomeDirectory/bin (read and execute permission)
   • JREHomeDirectory/lib (read and execute permission)
2. If you do not have an /opt/bmc directory, create it to complete the installation.
3. Ensure that the open files limit [ ulimit –n ] section of the shell is set to 16384.
   To do so, modify the /etc/security/limits.conf file.

Cause # It was unable to execute the driver command within /tmp/Utilities/Rik/driver.exe with SE Linux enabled

Resolution # SE Linux was enabled and disabling SELinux took care of the issue and install went successful.

Other workaround is to point out IATEMPDIR during install to point different temp directory than /tmp so that user do not have to disable SE Linux configuration.

Note: By default with SELinux enabled, you cannot run any binary from /tmp directory.
