Causes of steamapiunregistercallresult errors




Steamapiunregistercallresult is a function that is used by Steam games to unregister a callback object that was previously registered with SteamAPI_RegisterCallResult. A callback object is a piece of code that is executed when a certain event happens, such as when a game is downloaded, updated, or launched. SteamAPI_RegisterCallResult and SteamAPI_UnregisterCallResult are used to manage these callback objects and ensure that they are executed properly.


However, sometimes SteamAPI_UnregisterCallResult may fail or crash due to various reasons, such as:


Missing or corrupted steam_api.dll file




The steam_api.dll file is a dynamic link library file that contains the functions and data for Steam games. It is essential for running Steam games and communicating with the Steam client. If this file is missing or corrupted, SteamAPI_UnregisterCallResult may not work correctly and cause errors.


To check if your steam_api.dll file is missing or corrupted, you can follow these steps:


  • Go to the folder where your Steam games are installed (usually C:\Program Files (x86)\Steam\steamapps\common).



  • Find the game folder that is causing the error and open it.



  • Look for the steam_api.dll file in the game folder. If you don't see it, it means it is missing. If you see it, right-click on it and select Properties.



  • Go to the Details tab and check the file version and size. Compare them with the official version and size of the steam_api.dll file from this website. If they don't match, it means your file is corrupted.



  • If your steam_api.dll file is missing or corrupted, you can download a new one from this website. Make sure you download the correct version for your system (32-bit or 64-bit).



  • Copy the downloaded steam_api.dll file and paste it into your game folder. Replace the old file if prompted.



  • Launch the game and see if the error is fixed.



Outdated or incompatible drivers




Drivers are software components that allow your hardware devices, such as graphics card, sound card, or mouse, to communicate with your operating system and applications. If your drivers are outdated or incompatible with your system or Steam games, they may cause conflicts and errors with SteamAPI_UnregisterCallResult.


To update or reinstall your drivers for Steam games, you can follow these steps:


  • Press Windows + R keys on your keyboard to open the Run dialog box.



  • Type devmgmt.msc and click OK to open Device Manager.



  • Expand the category of the device that you want to update or reinstall (such as Display adapters).



  • Right-click on the device name and select Update driver or Uninstall device.



  • If you choose Update driver, select Search automatically for updated driver software and follow the on-screen instructions.



  • If you choose Uninstall device, check the box that says Delete the driver software for this device and click OK.



  • Restart your computer and Windows will automatically install the latest drivers for your device.



  • Launch the game and see if the error is fixed.



Malware or virus infection




Malware or virus are malicious programs that can infect your system and damage your files, settings, or registry. They can also interfere with your Steam games and cause errors with SteamAPI_UnregisterCallResult.


To scan and remove malware or virus from your system, you can follow these steps:


  • Download and install a reputable antivirus software (such as Malwarebytes) if you don't have one already.



  • Run a full system scan with your antivirus software and remove any detected threats.



  • Restart your computer and launch the game to see if the error is fixed.



Registry issues




The registry is a database that stores information and applications. It is used by Windows and Steam games to store various settings and preferences. If the registry is corrupted, damaged, or contains invalid entries, it may cause errors with SteamAPI_UnregisterCallResult.


To clean and repair your registry with a reliable tool, you can follow these steps:


  • Download and install a reputable registry cleaner program (such as CCleaner or Restoro) if you don't have one already.



  • Run the registry cleaner program and scan your registry for errors.



  • Review the scan results and fix the errors that are found.



  • Restart your computer and launch the game to see if the error is fixed.



Solutions for steamapiunregistercallresult errors




If none of the above causes apply to your situation, or if you have tried them all and still get the steamapiunregistercallresult error, you can try some of these solutions:


Solution 1: Verify the integrity of game files




Sometimes, the game files may be corrupted or missing due to various reasons, such as incomplete downloads, power outages, or disk errors. This can cause errors with SteamAPI_UnregisterCallResult when you try to launch or play the game. To verify and repair your game files, you can use Steam's built-in feature that checks for any problems and fixes them automatically.


To verify the integrity of game files, you can follow these steps:


  • Open Steam and go to your Library.



  • Right-click on the game that is causing the error and select Properties.



  • Go to the Local Files tab and click on Verify Integrity of Game Files.



  • Wait for Steam to scan and repair your game files.



  • Launch the game and see if the error is fixed.



Solution 2: Run Steam as administrator




Sometimes, Steam may not have enough access or permissions to run games properly. This can cause errors with SteamAPI_UnregisterCallResult when you try to launch or play the game. To grant Steam full access and permissions, you can run it as an administrator.


To run Steam as an administrator, you can follow these steps:


  • Close Steam if it is running.



  • Go to the folder where Steam is installed (usually C:\Program Files (x86)\Steam).



  • Right-click on Steam.exe and select Run as administrator.



  • Click Yes if prompted by User Account Control.



  • Launch the game and see if the error is fixed.



Solution 3: Disable antivirus or firewall temporarily




Sometimes, your antivirus or firewall software may interfere with Steam games and cause errors with SteamAPI_UnregisterCallResult when you try to launch or play the game. This can happen if your antivirus or firewall software mistakenly identifies Steam games as threats or blocks their network connections. To prevent this from happening, you can disable your antivirus or firewall software temporarily while playing Steam games.


To disable your antivirus or firewall software temporarily, you can follow these steps:


  • Find your antivirus or firewall software icon on your system tray (usually at the bottom right corner of your screen).



  • Right-click on it and select Disable, Turn off, Exit, Quit, or a similar option.



  • Select a time period for which you want to disable it (such as 15 minutes, 1 hour, until restart, etc.).



  • Launch the game and see if the error is fixed.



  • Remember to enable your antivirus or firewall software again after playing Steam games.



Solution 4: Reinstall Steam and the game




If none of the above solutions work for you, you may have to uninstall and reinstall Steam and the game completely. This can help you get rid of any corrupted or outdated files that may cause errors with SteamAPI_UnregisterCallResult when you try to launch or play the game. However, this solution will also delete all your game data and settings, so make sure you back them up before proceeding.


To uninstall and reinstall Steam and the game completely, you can follow these steps:


  • Open Control Panel and go to Programs and Features.



  • Find Steam in the list of programs and click on Uninstall/Change.



  • Follow the on-screen instructions to uninstall Steam from your computer.
