Update tools & Vsield drivers from a vapp

Hi all,

I need to update the vmware tools on a group of virtual machines within a vapp to include the vshield drivers. with the following switches

/v "/qn REBOOT=R ADDLOCAL=VMCI,VShield REMOVE=Hgfs"

how would i go about scripting this so that is applied to each virtual machine in the vapp?

I've tried this below but get an error so would appreciate some guidance.

Thanks

Alex
