How to Fix Application Load Error 3:0000065432?

When trying to start games on Windows, users sometimes run into the “Application Load Error 3:0000065432” This issue commonly shows up as a sudden shutdown of the game or a failure to launch after the game’s icon briefly pops up in the taskbar. It points to a general problem with the game application’s loading process, which could originate from various issues related to the Steam client or the game files themselves.

Antivirus software conflicts or improper permissions in the Steam folder are common causes of this error because they prevent the game files from loading properly. Common causes include incorrect antivirus settings or installing the game in a location outside the standard directories.

If you’re experiencing this error, follow this article’s steps to fix the problem. The solutions below have helped other users solve this error.

1. Verify the Game’s Integrity

Checking the game’s integrity lets you look for any missing or damaged files in the game’s installation and fix them by downloading and replacing those files. This process confirms that the game has all the essential, required data, which can fix launch issues. In short, it returns the game files to their original condition, enabling the game to function properly.

  1. Open the Steam client and go to the Library tab.
  2. Right-click on the game showing the error and choose Properties.
  3. Switch to the Installed Files tab and select Verify Integrity of Game Files.
  4. After the verification is complete, start the game again to see if the error is gone.

2. Reinstall Steam

Reinstalling Steam might fix the error by replacing broken Steam files with new, undamaged ones. The reinstallation process wipes out any errors in the previous setup and reconstructs the Steam file organization, potentially eliminating software issues that prevent games from loading. A fresh installation can also clear up problems that built up over time with the old version.

  1. Make sure the Steam client is entirely shut down.
  2. Press Windows key + R, type appwiz.cpl in the Run prompt, and press Enter to go to Programs and Features.
  3. Look for the Steam entry, right-click on it, and select Uninstall.
  4. Restart your PC.
  5. Once the computer restarts, visit this link (here) and click Install Steam to download the installer.
  6. Run SteamSetup.exe and follow the instructions to put Steam back on your computer.

After reinstalling, check if the game still shows the error. If it does, try the next fix.

3. Disable DeepGuard Feature of F-Secure (if applicable)

Turning off F-Secure’s DeepGuard feature could solve the issue as this tool monitors installed software for unusual behaviour, which might incorrectly flag a legitimate game or app launched via Steam as dangerous, blocking it or interfering with its operation.

Once you disable DeepGuard, it stops this real-time surveillance for the game, possibly preventing wrongful alerts and letting the game start without errors.

  1. Open F-Secure Internet Security and choose Computer Security.
  2. Hit Settings, then head to Computer > DeepGuard.
  3. Un-tick the Turn on DeepGuard checkbox and confirm your changes.
  4. Reboot the game to see if the issue is fixed. If you still encounter the error, use the next method.

4. Investigate 3rd Party AV Interference (if applicable)

Some users have found that their external security application was to blame, as these programs can sometimes block an app’s attempts to connect with outside servers, leading to the error.

If you have a third-party antivirus program other than Windows Defender, try turning off the real-time protection temporarily before starting the game. The steps to do this vary by security software, but usually, you can do it through the system tray icon.

After switching off the third-party AV, open the game to see if the error is gone.

Keep in mind that an external firewall can cause similar issues. Unlike antivirus software, which stops its security rules when you disable real-time protection, firewalls keep their rules active. To completely exclude a third-party firewall as the cause, you might need to uninstall it.

Note: Uninstalling your third-party security software won’t leave your system unprotected. Windows Defender will kick in automatically, and it’s known to be less interrupting while still providing good protection.
