You have to complete The Kagrumez Trials to open the room with the bow. If you have done the quest some people find it on the floor not the table have a good look around (maybe use a shout or spell to knock it into view). Otherwise the only thing to try on a console is reload or on a PC spawn the bow with a console command.
