Superb game but unworthy installation.

The game is visually stunning (5 stars), but it took me four facilities to achieve appreciation (so 0 star or average of 2.5). Thank you to the editor! Hoping that it will be useful, here's how I proceeded with the fourth system (Windows 7 64).
LA Noire launch the DVD and let install Microsoft C ++ and Social Club. Then choose custom installation and rename the target directory with ... / Lanoire (no spaces). Continue the installation until the end.
Do not start the game, otherwise it downloads a patch that is not working.
Download the other patch (the one that worked for me) [...] and place it in the "Lanoire" directory. Open it as administrator (right click) and click update. Start the game from the "Lanoire" directory by cutting the internet (over dune previous installation, starting the game, javais returned the key and Social club identifiers). It was then for me.
