Question: I downloaded the PC version of L.A. Noire from Steam and I can't launch the game! When I try to run the game from the launcher it brings me back to the launcher in an endless loop, or sometimes it crashes altogether after appearing to re-perform part of the setup. How can I fix this?
Answer: In Windows Vista/7, it may be necessary to turn off UAC (User Account Control) and/or run Steam as an Admin.
Turn off UAC:
Open Control Panel
Select User Accounts
Select 'Change User Account Control Settings'
Change the slider to Never Notify
For further information on User Account Control configuration, see:
