Attempting to apply CA VM:Secure 3.2 PTFs published after RSU-1801 (PTF SO01600), VMSES/E reports the PTF(s) cannot be applied because PTF SO01589 is a pre-requisite and is not applied.
PTF SO01589 is installed by installing CA VM:Secure 3.2 RSU-1801 (PTF SO01600) and you do not have RSU-1801 installed.
