Fix: Error Code 0x8007042b When launching Xbox games

Error code 0x8007042b can be caused by many different reasons. According to research on various forums, this error mainly occurs due to inappropriate permissions, incorrect time, and corruption in the game files.

Before we move on to the solutions, try restarting the computer. Restarting the computer is a way to restart the services that are required to run Xbox Game Pass. Therefore, it is always advisable to start by restarting the computer.

2. Run the Xbox Game Pass as an administrator

Running the game with administrator permissions prevents firewall interference and grants access to all DLL and other files that are required to run the game properly. To do so, follow the steps.

1. Simply right-click the game and select Run as administrator.
2. If the game is launching, configure the game to always run as administrator by navigating to the compatibility settings. For that, right-click the game and go to Properties.
3. Then, go to Compatibility, and tick Run this program as an administrator.
4. Once done, click Apply and click OK.
5. Now you will be able to launch the game always as an administrator.

3. Set the Date and time correctly

Make sure your time and time zone is set correctly because error code 0x8007042b also occurs when you have an incorrect time set on the device. We recommend setting the time automatically rather than setting it manually. To do so, follow the steps:

1. Right-click the Start Menu and select Settings to open it.
   
2. Navigate to Time & language from the left sidebar.
3. Navigate to the Date & time settings.
   
4. Turn on the Set time automatically.
5. Make sure the time zone is set, then click Sync Now to sync the time with the Windows server.
   

4. Update the Windows

Having an outdated version of Windows can also have a major impact on the occurrence of this error. If your Windows software is outdated, it’s possible that your Windows components, security features, and drivers are outdated as well. This might be why Xbox games are not launching. Therefore, make sure to update your Windows before proceeding to the next steps.

1. To update the Windows, launch Settings by pressing Win + I on the keyboard.
2. Then, head to the Windows update and click Check for updates.
   
3. Then, click Download & Install.
4. Once all the updates are downloaded, install them by restarting the computer.

5. Restart all Xbox services

The Xbox services run in the background to manage the tasks that the Xbox games require to launch properly. If one of the Xbox services is not running, the games might not launch and cause this error. Therefore, try restarting all the Xbox services to ensure they are running properly. To restart the Xbox services, follow the steps:

1. Launch the Run Window by using the key combination Win + R.
2. Type services.msc and press Enter to open the services Window.
   
3. Here find the Xbox services. For that, right-click the Xbox service and select Properties.
4. Change the Startup type to Automatic.
5. Click Start If the service is stopped.
6. Then, click Apply and click OK.
   
7. Repeat this process for all the Xbox services.
8. Once done, launch the Xbox game and check for the error.

6. Reset Microsoft Store

This error can also occur if there is a problem with the Microsoft Store cache. Every application creates cache files to reduce the loading time. However, sometimes these cache files get corrupted, which causes various errors. In this case, you can try resetting the Microsoft Store to clear the cache files. To do so, simply follow the steps.

1. Launch the Run Window by using the Win + R keys simultaneously.
2. Then, type wsreset.exe in the search box and click OK to reset the Microsoft store.
   
3. Once done, check if the error is fixed or not.

7. Reset or Repair the game

Since we have tried every solution, it is possible that you have corruption in your game files. In this case, you can try resetting or repairing the game, which will automatically restore the corruption from your game files. To do so, follow the steps:

1. Navigate to Settings by right-clicking the Start Menu.
   
2. Go to Apps > Installed apps and locate the Xbox game, causing the error.
3. Click the three dots and select Advanced options.
   
4. Scroll down to the bottom and click the Repair.
5. Once the game is repaired, launch the game to check the error. If the error persists, try resetting the app by using the Reset button.
   

8. Reinstall the Game

If resetting or repairing the game files did not work, the final solution you can try is reinstalling the game, which has actually worked for several users. Therefore, try reinstalling the Xbox game to see whether it fixes the error or not. To do so, follow the steps:

1. Open the Start Menu by pressing the Win key.
2. Type Add or Remove programs and hit Enter to navigate to the settings.
   
3. Here locate the game and click the three dots, then click Uninstall.
4. Once again, click Uninstall to confirm.
   
5. Once done, download and install the game from the Microsoft Xbox Game app.
