I have cloned my plesk server as it says at http://www.parallels.com/download/plesk/11.5 then I was going to preview this on cloned virtual machine but I cannot as I get parallels installer was updated then after it refresh to updated installer there is no way to preview 11.5 but to update 9.5 files (theres no reason to update) while I'm already at 11.0.9?
