If this is line 94
if [ "$SUBPRODUCT" = "AppRM" ]; then #AppRM
just try editing the 'omnisetup.sh' file and commenting thsi line out. Also search for any other occurrances of AppRM, and comment out those lines too
AppRm is an abandoned product, and, I believe, this should not be in the Installation script at all
I also recommend that you run the scripts 2 times once for the Cell Manager
omnisetup.sh -CM
and one for the Installation Server
omnisetup.sh -IS
