Answer: If your patch times out or fails to install, here is how to retry the patch procedure:
1.Navigate to C:\Program Files\Rockstar Games\L.A. Noire
2.Remove any file with a .patched extension
3.Remove Social Club v1.0.5.0 Setup.exe
4.Run Patch_2382_02393_1.exe
5.Press Update
6.Start Game via launcher
7.If the same thing happens, uninstall and re-install the full game and attempt to patch. If the same problem happens, repeat steps 1-6 above after consulting the tips below.
Tips:
•Disable any anti-virus or firewall software that could interfere.
•When the patch fails, try to press the HOME key to bring up the Social Club menu and try to create a profile or log into an existing one.
•Be sure Run as Admin by right-clicking the LANLauncher executable, choosing to run as administrator.
•Be sure after force quitting L.A. Noire to go to Task Manager and end all of the L.A. Noire-related processes before attempting the manual patch or re-launch of the game. You may see Patch_2382_02393_1.exe still running and several versions of LANoire.exe.
•Make sure you are connected to the Internet and that port 443 is open. This is required to connect and patch the game.
•Uninstall and re-install the game using a default path on the boot drive.
•Try uninstalling and then reinstalling to either C:\Program Files\RockstarGames\L.A.Noire or C:\Program Files (x86)\Rockstar Games\L.A. Noire (Win7 64-bit)
Also ensure that you re-install or repair all of the required .NET/C++/DirectX components.
