To make it run on Windows 10:

1. Exit Steam
2. Start Steam with rightclick on icon "Run as administrator".
3. Launch the LA Noire and make sure the Adapter is at "Default" under options.
4. Click the Launch the game and it works.


Have your SocialVista mail/pass ready as you can't Alt_Tab or the game crashes and you need to restart your whole computer... (i learned it the hard way)

Hope it helps, the game is great!
