Self protection failed Error code: 4 · Issue #1567 - GitHub
The "Self Protection Failed Error Code 4" is a common issue encountered when using x360ce (Xbox 360 Controller Emulator), particularly with 2021 releases and online multiplayer fixes. It typically occurs when the software's security or integrity checks are blocked by system settings or antivirus programs. Review Summary: x360ce Error Code 4
While x360ce is a powerful tool for mapping generic controllers to XInput-supported games, the "Error Code 4" remains a frustrating barrier for users. This error often appears when the application cannot initialize its self-protection routine, frequently due to Windows Security flagging it as suspicious or conflicting with Online-Fix libraries in games like Elden Ring or Phasmophobia. Common Causes
Troubleshooting the "Self Protection Failed" Error Code 4 in x360ce (2021)
If you are a PC gamer using a generic controller, x360ce (Xbox 360 Controller Emulator) is likely your best friend. It allows your PC to "see" your budget gamepad as a standard Xbox 360 controller, ensuring compatibility with modern titles.
However, many users in 2021 began encountering a frustrating roadblock: "Self protection failed. Error code: 4." This error usually pops up when the application fails to initialize its security or driver-hooks properly.
Here is a comprehensive guide to understanding why this happens and how to fix it. What Causes Error Code 4?
In the context of the 2021 builds of x360ce (specifically the 4.x "All-In-One" versions), Error Code 4 typically relates to Virtual Bus Driver (ViGEmBus) issues or Permissions.
Missing Virtual Bus Driver: The modern version of x360ce requires the ViGEmBus driver to create a "virtual" controller. If this isn't installed or is corrupted, the self-protection check fails. Additional Tips
Administrative Restrictions: The app needs deep access to intercept input signals. Without admin rights, Windows blocks these actions.
Antivirus Interference: Windows Defender or third-party AVs often flag the "hooking" behavior of x360ce as malicious. Step-by-Step Solutions 1. Install or Reinstall ViGEmBus
This is the most common fix. The 4.x version of x360ce cannot function without the Virtual Gamepad Emulation Bus.
Open x360ce and go to the "Issues" tab. Often, the app will explicitly tell you the driver is missing and provide an "Install" button.
If that fails, download the latest ViGEmBus driver manually from the official GitHub repository. Restart your computer after installation. 2. Run as Administrator
Windows 10 and 11 have strict security protocols regarding applications that emulate hardware. Right-click your x360ce.exe file. Select Properties. Go to the Compatibility tab. Check the box: "Run this program as an administrator." Click Apply and OK. 3. Clear the Virtual Devices
Sometimes the "Self Protection" fails because a previous session left a "ghost" controller active in your system. In x360ce, navigate to the Settings or Devices tab.
Look for any "Hidden" or "Virtual" devices that are currently mapped.
Remove them, close the program, and restart it to let it re-initialize the virtual bus. 4. Visual C++ Redistributable Update
x360ce is built on C++. If your Windows installation is missing the latest Microsoft Visual C++ Redistributable (x64 and x86), the application components will fail to load, triggering generic error codes. Conclusion By following these steps, you should be
Visit the Microsoft support site and download the latest "All-in-One" redistributable package (2015-2022). 5. Add an Antivirus Exclusion
If the error persists, your Antivirus might be "protecting" the system by killing the x360ce process. Go to Windows Security > Virus & threat protection. Select Manage settings and scroll down to Exclusions.
Add the folder where your x360ce.exe is located to the exclusion list. Conclusion
The "Self protection failed error code 4" is rarely a sign of a broken controller; it’s almost always a software handshake issue. By ensuring the ViGEmBus driver is active and giving the app Administrative privileges, you should be back to gaming in no time.
If you are still seeing the error, consider downgrading to the 3.x (SDK) version of x360ce if your game is older (DirectInput), as the 4.x version is specifically designed for modern "Global" emulation.
Some third-party antivirus (Avast, McAfee, Bitdefender) actively blocks x360ce's "self-protection" feature because it looks like ransomware behavior (a program trying to modify its own executables).
This error occurs when x360ce cannot install or access its virtual driver because:
Right-click x360ce.exe → Run as administrator. This gives it permission to write DLLs and hook into processes.
Option A – Disable Defender’s driver blocking (Recommended temporarily)
Option B – Disable antivirus temporarily
