Is it trying to update GFWL or the game? If GFWL, you should be able to just install the latest version of GFWL.
I don't know if the client you linked to is the correct one. Could be some marketplace specific crap that you don't need. Try this: http://www.microsoft.com/games/en-us/live/pages/livelaunch.aspx
Edit: Actually your link should be fine too, the .exe it downloads has the same name so I assume it's the same thing.
If it's the game that needs to be updated, the manual patch is here: http://www.fileplanet.com/205510/200000/fileinfo/Batman:-Arkham-Asylum-Patch-v1.1
