Iwant to install ICN 3.0.4 but it fails on starting by showing this error:

=======================================================

Installer User Interface Mode Not Supported

Unable to load and to prepare the installer in console or silent mode.

=======================================================

I confirm if the X11-forwarding enabled

we are using AIX and not REDHAT evenif, we have executed these commands but the same issue:

rpm -qa | grep xorg-x11-fonts-Type1

rpm -qa | grep stix-fonts

what about websphere, we have 9.0.5

Ensure you have all the required rpms and libs:

You can also ensure the IATEMPDIR is set to a location that has ample space:

• On Unix, the installer does not prompt to pick another location; however the IATEMPDIR environment variable may be manually set to a location with sufficient temp space. To set the variable enter one of the following commands at the UNIX command line prompt before running this installer again:
• for Bourne shell (sh), ksh, bash and zsh:
• $ IATEMPDIR=/your/free/space/directory
  • $ export IATEMPDIR
• for C shell (csh) and tcsh:
  • $ setenv IATEMPDIR /your/free/space/directory

Why are you trying to install ICN 3.0.4? It is only covered by continuing support at this point. ICN 3.0.7 is the earliest release that is fully supported....and better still ICN 3.0.11 is the latest version and is a long-term support release.
