How to Fix Application Load Error 3:0000065432?

When trying to start games on Windows, users may encounter the “Application Load Error 3:0000065432.” This issue often results in a sudden shutdown or failure to launch, with the game’s icon briefly appearing in the taskbar. It indicates a problem with the game’s loading process due to issues related to the Steam client or game files.

This error is often caused by conflicts with antivirus software or improper permissions in the Steam folder, which prevent game files from loading correctly. Other causes include incorrect antivirus settings or installing the game outside standard directories.

Now that you know the causes, lets discuss the solutions.

1. Verify the Game’s Integrity

Verifying the game’s integrity checks for any missing or corrupted files in the game’s installation and fixes them by downloading and replacing those files. This process ensures the game has all the necessary data, which can resolve launch issues by restoring the game files to their original condition.

  1. Open the Steam client and go to the Library tab.
  2. Right-click the game with the error and select Properties.
  3. Go to the Installed Files tab and click Verify Integrity of Game Files.
  4. Once verification is complete, restart the game to check if the error persists.

2. Reinstall Steam

Sometimes, reinstalling Steam can resolve the error by replacing broken files with new, clean ones. This process clears errors from the previous setup and reorganizes Steam’s file structure, potentially fixing issues that prevent games from loading. Additionally, starting fresh can address problems that have accumulated over time with the old version.

  1. Exit the Steam client completely.
  2. Press Windows key + R, type appwiz.cpl, and press Enter to open Programs and Features.
  3. Locate Steam, right-click, and select Uninstall.
  4. Restart your PC.
  5. After restarting, visit this link and click Install Steam.
  6. Run SteamSetup.exe and follow the instructions to reinstall Steam.

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

3. Disable DeepGuard Feature of F-Secure

Disabling F-Secure’s DeepGuard feature may resolve the issue, as this tool monitors installed software for unusual behavior and might mistakenly flag a legitimate game or app from Steam as dangerous, blocking or interfering with its operation. By turning off DeepGuard, you stop real-time monitoring, which could prevent false alerts and allow the game to start without errors.

  1. Open F-Secure Internet Security and go to Settings.
  2. Navigate to Computer > DeepGuard.
  3. Uncheck Turn on DeepGuard and confirm changes.
  4. Restart the game to see if the issue is resolved.

4. Investigate Third-Party AV Interference (if applicable)

Third-party antivirus (AV) programs can sometimes cause disk errors or boot issues by blocking essential system files or processes. If an AV is overly aggressive, disabling or uninstalling it temporarily might resolve these conflicts and restore normal disk and boot functions.

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

Keep in mind that an external firewall might cause similar issues. Unlike antivirus software, which suspends its security rules when you disable real-time protection, firewalls maintain their rules. To fully rule out 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 automatically activate and is known to be less intrusive while providing good protection.

    I’m my case it was “Deep Guard”. Sent a sample to F-Secure só they can fix this in future versions.

      Have you tried deleting the executable file of the program you are trying to run? If not first of all delete the .exe file from the game/program folder and after that open steam and verify the integrity files that way Steam will be forced to download original and fresh executable file replace any corrupted file which can potentially fix your Issue. Keep me updated!

      Did you verify the integrity of the game files? Please completely restart steam and try verifying again. Also, can you tell me do you have Windows Defender?

    This was giving me FITS with “No Man’s Sky” from Steam, and neither Steam, nor Hello Games could offer any help beyond the standard “Check Game files and update your drivers” form letters.Turns out that Deep Guard was, in fact, the culprit. Apparently, F-Secure is hiding inside Spectrum Internet’s “Security Suite” because I found Deep Guard there, though it swore it hadn’t blocked my game. As soon as I turned it off – BOOM. NMS works again.I’m -Seriously- disappointed that Steam (non)Support didn’t have this information for me first, even if only a link to this page or something similar. ANYTHING would have been better that “Lol, we don’t know…¯_(ツ)_/¯”I may actually write them a physical letter.

    Hey,
    I tried to reinstall steam, but now I have the problem that all my previously installed games are gone. Do I really have to reinstall my entire library or is there an other option?

      When you completely uninstall Steam it basically unregisters the libraries attached to your Steam copy. It is possible that you can get your entire Steam library back. Keep in mind you can only get back the games on the library if you have the libraries on your computer/disk. if you don’t have the libraries you will have to reinstall everything. Here are the steps please follow and let me know:-

      1. Open Steam.
      2. Click on the “Steam” button in the top left corner.
      3. Now click on the “Settings” option.
      4. Now click on the “Download” tab in the Settings Menu.
      5. Click on the button “Steam Library Folders”.
      6. Now click on the “Add Library Folder” option.
      7. Now simply find and select the existing Steam libraries in your disk and it should work.

    All I did was the following:
    1. Right click on Security Suite (F-Secure) and click on open settings
    2. Disable Virus Protection and Deep Guard & ran Skyrim and it worked.
    3. I then exited out of the game and went back to the Virus & Threats Menu and put everything back on.
    4. Go to the Deep Guard and right below it, it will say View Blocked Application and click it.
    5. It will bring you directly to the Blocked Tab, but you will want to click on the “Excluded” Tab right next to it.
    6. On the bottom of the menu, you have 2 options, Add New and Remove. Click “Add New”, go to your steam main folder, example (D:Program Files (x86)Steam) and click ok.
    7. Check all your virus protections to ensure they are all on and you should be G2G.Please note: I’m not a IMO, but everything above is step by step of how I fixed mine, so I hope this helps people out with the same issues! Also, I didn’t reinstall steam since I had this happen with Age of Empires in the past as well. May want to look up and see if there are issues with the C++ on your PC as well.
