I installed Bioshock 2 and GTA 4 EFLC yesterday and after signing in GFWL gave me an error 80072751 when it tried to update the game. After searching these forums I tried several things -
Allowed through Windows Firewall
Opened ports on router (even though uPnP is enabled)
Disabled anti-virus (Avast 5)
Ran IGD test (passed)
None of these solved the problem so I manually downloaded and installed Bioshock 2 (patch 3) and GTA 4 EFLC 18.104.22.168. Now GFWL won't even sign in on starting the game. The event viewer shows -
1, 0, 0, 1

EDIT: Forgot to add that Dow2: Chaos Rising, which was working earlier is also giving the same error now.
I'm using Win 7 x64.
