Many affected users have reported that restarting the system can fix the error code 0x1. This suggests that the error could also result from a transient bug, which might be resolved by a simple restart. Before you start troubleshooting, we highly recommend restarting your computer.
1. Run Minecraft.exe as an Administrator
Executing a file as an administrator grants the program all necessary permissions it needs to function adequately. When you run the program as an administrator, you allow the application to make changes to files and settings at the administrator level.
2. Update Windows
An outdated version of Windows can often cause compatibility issues with Microsoft applications such as Minecraft. To avoid such problems, it’s important to keep your system up to date.
3. Delete Minecraft Game Files
Clearing Minecraft’s game and cache files, which sometimes become corrupted, is another straightforward solution to prevent crashes and eliminate error messages. Here, we will remove the Minecraft folder from the AppData directory, which contains the game files and cache. After deleting the folder, simply starting Minecraft will prompt the creation of a new folder.
4. Reinstall the Java Version and Add Java to Environment Variables
Minecraft relies heavily on Java for its game logic, graphics, and sounds, and also allows players to mod the game using Java. If the Java Development Kit (JDK) installed on your PC is problematic, you may experience crashes along with the error code 0x1. The solution below addresses reinstalling Java and adding it to Environment Variables, ensuring Minecraft can properly use Java.
5. Download the Latest .NET Framework
The .NET Framework is crucial for the operation and development of Windows applications. If you have an outdated or corrupted .NET Framework, it could prevent Minecraft from running smoothly.
6. Download Bedrock Launcher Lite
Bedrock Launcher Lite is an alternative, unofficial Minecraft launcher. While it requires having the official Minecraft installed, it can be a solution if there are issues with the standard launcher. Moreover, Bedrock Launcher Lite allows you to play any version of Minecraft, old or new. Download and install Bedrock Launcher Lite from its official website to begin playing Minecraft on your PC.
7. Repair or Reset Minecraft
Applications installed from the Microsoft Store can be repaired or reset. The repair option checks and mends application files, while resetting removes application data and can often remedy issues. This guide has provided various solutions that have helped users fix Minecraft Error Code 0x1. If all else fails, you might consider reinstalling Minecraft. Given that you have already tried resetting or repairing the game, reinstalling may not resolve the problem. In such cases, you can proceed to troubleshoot your network connection. If the problem still cannot be resolved, you may need to contact your ISP (Internet Service Provider).
