İ will try your solution but before that I found out detail of error message from script which is called name "Detect" and it placed in iso.
# Verifies that the ksh supplied in "$1" is PDKSH of the correct
# version (by checking the value of $KSH_VERSION)
[ "`$1 -c 'echo $KSH_VERSION' 2>/dev/null`"x = '@(#)CV PD KSH v5.2.14 12/03/08 [ARRAY EXTENDED TO 16K]'x ] && return 0
testPdKsh $1 && return 0
echo "*** Wrong version of ksh: $1."
Would it be possible the resource of problem happens wrong PDKSH version on aix?
