Attempting to apply CA VM:Tape 2.0 PTFs published after RSU-1801 (PTF SO00935), VMSES/E reports the PTF(s) cannot be applied because PTF SO00891 is a pre-requisite and is not applied.
PTF SO00891 is installed by installing CA VM:Tape 2.0 RSU-1801 (PTF SO00935) and you do not have RSU-1801 installed.
