How to Fix Application Load Error 3:0000065432

Through this, Windows users may receive the "Application Load Error 3:0000065432" when trying to open any game. Common manifestations of this problem are when the game icon briefly shows up in the taskbar and then all of a sudden closes, or it doesn't load at all. This error simply indicates that either the game's files or the Steam client is acting fussy to load.

The incorrect permission in the Steam folder, and some problems with the antivirus are the most common causes that may lead to this error and would prevent game files from loading correctly. Besides these common possible causes, there are a few more potential reasons, which include installing the game in an unsupported directory and using the wrong antivirus settings.

We can now talk about the remedies since you understand the problems.

1. Check the Honesty of the Game

This checks the integrity of the game by looking for corrupted or missing installation files and updating them by downloading and replacing. This process will ensure the game has all necessary data by reverting the game files to their default state and may resolve launch issues.

Open the Library tab in the Steam client.

Locate the game in the list, right-click on it, and go to Properties.

From the Installed Files tab, click on Verify the Integrity of Game Files.

When verification is done, open the game once more to check if the problem has been resolved.

2. Steam Reinstallation.

Many errors can be fixed by reinstalling Steam, as the process replaces corrupted files with fresh ones. Performing this operation cleans up the file structure of Steam and removes errors from the prior setup in order to fix problems with games failing to load. Also, if you start over with a new version, you may fix all issues that have built up with the previous one.

Completely log out of Steam.

In the Run dialog that opens with the Windows key + R, type in appwiz.cpl and click the Enter key to open Programs and Features.

Right-click on Steam and choose Uninstall from the context menu.

Restart your system.

Upon restart, visit this link and click on Install Steam.

Run the SteamSetup.exe to reinstall Steam.

After that, check whether the error message is still displayed in the game or not. It means reinstalling is done; now go for the next solution.

3. Disable DeepGuard Protection of F-Secure

If all else fails, you can sometimes bypass this by disabling the DeepGuard feature of F-Secure. This feature will monitor software installed on your computer for suspicious activity and may falsely classify the legitimate Steam game or application as malicious and block the app's functionality. If you do not want these false alarms - if the game should launch seamlessly without incident - then now is the time to disable the DeepGuard real-time monitoring feature.

Open your F-Secure Internet Security and open Settings.

Click on Computer, then click on DeepGuard.

Uncheck the box saying Save your changes and turn on DeepGuard.

Now, try opening your game again. It may get resolved now.

4. Research possible interference by third-party AVs, if necessary.

If antivirus software of third-party companies has blocked any system file or process, which in fact was necessary, it will result in disk failure or problems in booting. The overaggressive approach by antivirus programs leads to the solution of such problems by disabling it or uninstalling it for the time being; the normal functioning of your disk or boot gets restored. 

Now, after having turned off the third-party antivirus application, launch the game again and check whether this has fixed your problem.

Keep in mind that outside of the network, a firewall could also trigger these very same problems. Unlike antivirus programs, firewalls continue applying their security policies even when you already turn real-time protection off. In this regard, to entirely rule it out as a cause, you might want to uninstall a third-party firewall.

Note that your system is still going to be secured after removing your third-party security software. With Windows Defender automatically enabled, you get a less intrusive security function that seems to be as effective.

By the end of these steps, you should be able to trace what may be causing Application Load Error 3:0000065432 and how you can get the application up and running.
