you need to be right over the Forcas System when you enter your ship. Essentially, when the quest wizard pops up explaining what to do, you need to turn your engines off as soon as you click 'continue', then enter your ship, head to the crew deck, then the mess hall.
setup a floor trophy and the option to place it should now be there.
1; I dont believe you do actually need to be in orbit of Forcas III to do it, but it has been a while.
2; This aprt of the mission was removed (moved I think), and so is no longer needed.
3; (And bearing in mind that I'm not like most peaople, so I wont swear, just use a lot of exclamation amrks,) 3 years!?!?!?!??!?!!? I suppose it is kind of understandable, as it is your first post, but still, a 3 year necro?
EDIT: Just remembered, it is now a optional mission.
