2) Click Account and click the Change button under Beta participation.

Many players reported to solve L.A. Noire not launching after they disable Desktop Game Theatre while SteamVR is active. Give it a shot and see if this fix works for you.

1) Launch Steam and click the Library tab.

2) Right-click L.A. Noire from the game list and click Properties.

3) Untick Use Desktop Game Theatre while SteamVR is active. Then, click Close.

Restart L.A. Noire and check if it starts without error. If the not launching problem persists, don’t despair. There is the last fix.


Fix 6 – Update your graphics driver

Wrong or outdated graphics driver can trigger various gaming annoyance and completely ruin the playing experience. To make your games run perfectly all the time, it’s essential that you install the up-to-date graphics driver.

You can visit the manufacturers’ websites such as AMD or NVIDIA to download the latest graphics driver manually. But if you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to a flagged graphics driver to automatically download the correct version of this driver, then you can manually install it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

You can do it for free if you like, but it’s partly manual.
The Pro version of Driver Easy comes with full technical support.
