Fixing Application Load Error 5:0000

Here’s a step-by-step guide to troubleshoot and resolve the Application Load Error 5:0000 for Fallout New Vegas:

Method 1: Delete Steam’s AppCache Folder and Temporary Files

Why This Works:
Temporary files and cache can become corrupted and cause various issues with Steam and your games. Clearing these can resolve conflicts and reset your Steam client.

Steps:

1. Delete Steam’s AppCache:

• Open Windows File Explorer and navigate to C:\Program Files (x86)\Steam.
• Find the appcache folder and delete it.

1. Delete Temporary Files:

• Press Windows Key + R to open the Run dialog box, type %temp%, and press Enter.
• Select all files and folders and delete them. You might need administrative permissions for some files.

After clearing these files, restart Steam and attempt to launch Fallout New Vegas again.

Method 2: Verify and Repair Game Files

Why This Works:
Corrupt or missing game files can lead to various errors. Verifying and repairing game files can fix these issues by replacing any problematic files.

Steps:

1. Open Steam and go to your Library.
2. Right-click on Fallout New Vegas and select Properties.
3. Navigate to the Local Files tab and click on “Verify Integrity of Game Files.”

Steam will check the game files and replace any missing or corrupted files. This process might take some time.

Method 3: Run Steam as Administrator

Why This Works:
Running Steam with administrative privileges can resolve issues related to permissions that might be preventing it from accessing game files.

Steps:

1. Close Steam completely.
2. Right-click on the Steam shortcut and select “Run as administrator.”
3. Try launching Fallout New Vegas from Steam.

Method 4: Reinstall the Game

Why This Works:
If the game files are severely corrupted or if other fixes don’t work, reinstalling the game can ensure you have a fresh set of files.

Steps:

1. Uninstall Fallout New Vegas from Steam by right-clicking on the game in your Library and selecting “Uninstall.”
2. Restart your computer.
3. Reinstall Fallout New Vegas from Steam and check if the error persists.

Method 5: Check for Mod Conflicts

Why This Works:
Mods can sometimes cause conflicts or corrupt game files. Ensuring mods are properly installed or disabling them can help resolve the issue.

Steps:

1. If you use mods, try disabling them or removing them temporarily.
2. Launch the game to see if the error is resolved.

Method 6: Copy Steam.exe to the Game’s Folder

Why This Works:
If the Steam and game installation paths are mismatched, copying the Steam executable to the game’s folder can help establish the correct path.

Steps:

1. Navigate to C:\Program Files (x86)\Steam and copy steam.exe.
2. Go to the game’s folder, usually found in C:\Program Files (x86)\Steam\steamapps\common.
3. Paste steam.exe into this folder.

Method 7: Use Command Prompt to Link Steam and Game Folder

Why This Works:
Creating a symbolic link can trick Steam into recognizing the game’s installation path correctly.

Steps:

1. Open Command Prompt as an administrator.
2. Type the following command to navigate to the game folder: cd "C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas".
3. Create a symbolic link by typing: mklink "steam.exe" "C:\Program Files (x86)\Steam\steam.exe".

If none of the above methods resolve the issue, contacting Steam or Bethesda Support might be necessary. They can provide further assistance or identify if there’s a broader issue affecting multiple users.

Steps:

1. Visit the Steam Support page or Bethesda Support page.
2. Submit a support ticket detailing your issue and the steps you’ve already taken to try and resolve it.
