how to install mcafee access protection retrospectively

[Uraken]

Hi all i have mcafee AV 8.5 and am using epolicy ochestrator, when we rolled out mcafee to the work stations for some reason it seems that the access protection was not included, does anyone know if i can 'add' it to the clients on the network (mostly xp) without having to visit each machine and do a fresh install with the access protection enabled this time around?

 

as always thanks in advance.
