I keep getting a "The Launcher cannot query DirectX. Please update DirectX by installing the latest redistributable" error message when launching L.A. Noire.
I'm on Windows XP, and this is the Steam version of the game. GPU: NVIDIA 9800 GTX+, running 285.x drivers (the newest available for XP).
Problems started after the most recent patch (the patch that added DirectX 11 support... but I'm on XP, so whatevs).
Pre-patch, I would get the problem; the launcher would crash, but then the game would start anyway, so I didn't care, but now it doesn't launch at all. I can't downgrade retroactively (as far as I know?) because it's Steam, so I don't have the original media.
I've tried uninstalling and reinstalling DirectX, launching the game directly, launching the game as admin (I'm running as admin already, but I do "Run As" and uncheck the "protect this computer box"), launching Steam as an admin, validating the game cache, re-downloading, and reinstalling. Nothing works. I've tried disabling my anti-virus (Avast) (
C:\Program Files\Steam\steamapps is already whitelisted). I tried downgrading my GFX driver to the 280.x version.
