Information Voice acting and Pip-boy sounds (and possibly others) can not be heard, while the radio and movement can.

Fix Windows Sound Options

Information Can be fixed by correcting the number of sound channels in the configuration of your playback device in Windows.

Application load error P:0000065434[edit]

Information This happens when you start the launcher.

Fix Launcher doesn't open

  1. Rightclick the game in your Steam library and select "Properties"
  2. Select the tab "Local content" and click "Verify integrity of game cache". This might be necessary several times. Steam will download the missing/corrupt files.

Game Crashes on Startup (NVSE installed properly)[edit]

Information This happens when you start the game, and have mods that utilize NVSE. (New Vegas Script Extender)

Fix Crashes on Startup (NVSE installed properly)

  1. Rightclick nvse_loader in the Fallout New Vegas installation folder and select properties.
  2. Select the tab "Compatibility" and click "Run this program as administrator" and apply.
Information This could also be the result of mods attempting to change the same object.

Player "Sliding"[edit]

Information Character will continue to move or "slide" a bit sometimes even after they have stopped moving. Note that this should not be confused for the game engine forcing characters to take a full step when moving.

Fix Player "Sliding"

  1. Open Control Panel.
  2. Navigate to Keyboard settings (NOTE: You may have to change your view from "Category" to "Icons" in order to access Keyboard settings)

  2. Search for a file you want disabled with a .nam extension.
  3. Rename or delete the selected file.
  4. Repeat for any file you want disabled.

Application load error 5:0000065434[edit]

Information You get Applicaton load error 5:0000065434, when launching the game in any other way than through Steam. The cause for this is inappropriate Steam AppID being used. This can happen when you have a Polish, Czech or Russian version of the game.

Fix Installation of Fallout NV Extenders

Information This method only applies to PL/CZ/RU versions of the game. If it fails try one of the methods below.
Information This method involves installing two extensions. While being mods, they are considered essential.
  1. Download New Vegas Script Extender and install it according to the ReadMe file found in the archive.
  2. Download 4GB Fallout New Vegas and install it by extracting the .dll and .exe files into your Fallout NV installation folder.
  3. Create a shortcut to fnv4gb.exe in your Fallout NV directory and add -SteamAppId 22490 as a launch parameter. Shortcut should now resemble:
    "C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas enplczru\fnv4gb.exe" -SteamAppId 22490
  4. Use this shortcut command line as an example. It can be used to launch the game through Nexus Mod Manager, Mod Organizer and possibly other launchers.

Fix Symbolic link creation[7]

Information This method creates a symbolic link between where the game is installed, and where it "thinks" it is installed. It allows using the correct path without moving the game files.
  1. Open a Command prompt using "Run as Administrator" (Start>All Programs>Accessories>Command prompt).
  2. At the prompt type
    CD "C:\Program Files (x86)\Steam\SteamApps\common\"
    and press Enter (if the 'common' folder does not exist, create it).
  3. The command prompt should show the above path (if not, check if the folder exists).
  4. Next, type
    mklink /d "Fallout New Vegas" "D:\Steam\SteamApps\common\Fallout New Vegas"
    and press Enter (change the example path to your Fallout New Vegas installation folder).
  5. Recreate any shortcuts using the new "proper" path (i.e. C:\Program Files (x86)\Steam\SteamApps\common\Fallout New Vegas\FalloutNVLauncher.exe).
  6. Reconfigure your mod managers to also include the changed path.

Fix Game reinstallation

Information This method moves all the game files to the default Steam folder. Make sure you have enough disk space before doing this.
  1. Uninstall the game.
  2. Install the game, this time in the default Steam folder. Often:
    C:\Program Files (x86)\Steam\SteamApps\common\

Game crashes on intro movie on Lenovo machines[edit]

Information When selecting new game when playing on some Lenovo PCs/laptops, a second of the introduction movie is played then the game crashes.
Information This problem is caused by Lenovo's Onekey Theatre software (changes screen color and sound presets) conflicting with the game.

Fix Stop Onekey Theatre

  1. Open the Task Manager.
  2. End the process for OnekeyStudio.exe and OnekeySupport.exe.
Information Onekey Theatre's functions and any associated hotkeys on your machine will not work until the application is started again (can be accessed through the Lenovo folder in the Start menu).
