L.A. Noire How to get LA Noire to start in 3 steps

Download DirectX

 
Since the directX version that came with the game is faulty somehow and fails to install, just download the needed version at www.microsoft.com – https://www.microsoft.com/en-us/download/details.aspx?id=8109. 
 
Extract to a folder and install. 
 
 

edit registry

 
 
For some reason, if you start the game, it also starts an “error handler”. 
But if your game is not installed under the same drive letter as your steam installation, this can also cause problems. 
 
Run the regestry editor (regedit.exe) as an administrator. 
 
Check for the registry key 
 
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{1ac1a5cc-a7fd-3829-8e04-7e576ee57612}\inprocserver32 
 
and it´s sub-entries. There you will find two entries named “codebase” which have drive letters. Change those drive letters to the letter you installed the game on. 
So, for example, if it says file:///C:/… but your game is installed on drive G: you should change the drive letter to G. Only the drive letter, change nothing else. 
 
 

run steam as administrator

 
Title says it. Do it. The game should start now. 
 
 

if the game starts, but is stuck in low resolution / crashes when changing resolution

 
 
 
When you can´t chose a higher resolution in-game without crashing the game, try the following: 
Go to 
 
%HOMEPATH%\Documents\Rockstar Games\L.A. Noire 
 
there you should find the games´ settings.ini, there, the graphic options are stored. 
 
1) 
You can enter your preferred resolution like shown, where the 3rd number is the refresh rate / Hz. Don´t expect all values to run well; with the settings as shown, the game runs perfectly smooth on my system. 
 
2) 
Change DirectX 9 to 11 as shown. 
 
Have fun playing the game in high resolution.
