Alternatively, download the official, latest release of the directly from the Nefarius Software Solutions GitHub repository and install it manually. 5. Move x360ce Out of System Folders
Before fixing the error, let's understand the tool. x360ce (Xbox 360 Controller Emulator) is a open-source driver and application that tricks your Windows PC into thinking any game controller (PS4, PS5, Logitech, generic USB, or even a fight stick) is an official Microsoft Xbox 360 controller.
Unlike older versions (3.x) that relied on placing a xinput1_3.dll file directly into the game folder, the newer x360ce application creates a virtual Xbox 360 controller at the system level. To achieve this, it installs a virtual bus driver called (Virtual Gamepad Emulation Bus).
Windows Defender or third-party security suites flag the injection behavior as malicious.

The year is 2021, and Alex is finally ready to dive into a late-night gaming marathon. After a long day, they settle into their chair, plug in their generic gamepad, and fire up to make sure the controller actually works with their new game.
In 2021, x360ce transitioned from a simple application-specific DLL injector (the old 32-bit/64-bit local files) into a global, system-wide Virtual Gamepad Emulation framework. To do this safely, the software utilizes a virtual driver called (Virtual Gamepad Emulation Bus).
If the application is in a protected folder like C:\Program Files , move the entire x360ce folder to a non-restricted location (e.g., C:\x360ce ). 3. Resolve Software Conflicts
Error Code 4 can occur if the virtual driver that x360ce relies on is broken. ViGEm (Virtual Gamepad Emulation) handles the "emulation" part.
However, many users in 2021 began encountering a frustrating roadblock: This error usually pops up when the application fails to initialize its security or driver-hooks properly.
Download the latest official release of the directly from the official Nefarius Virtual Grid Gaming Github repository.
Open x360ce and go to the tab. Often, the app will explicitly tell you the driver is missing and provide an "Install" button.
