If you are trying to run a modern game on Windows 7, you may encounter the infamous xinput1_4.dll error (Error Code 126). This error prevents the game from launching and can be frustrating, especially since xinput1_4.dll is designed for newer versions of Windows. In this guide, we explain why this error occurs and provide a reliable workaround for Windows 7 users.

Why xinput1_4.dll Causes Errors on Windows 7

The xinput1_4.dll file is part of newer DirectX components introduced alongside Windows 10 and DirectX 12. Since Windows 7 does not natively include this DLL, any game or application expecting it will fail to start, showing messages like:

“The program can’t start because xinput1_4.dll is missing from your computer.”

Understanding this limitation is key: Windows 7 cannot fully support xinput1_4.dll, so the solution focuses on bypassing the DLL check rather than providing the full functionality.

How to Fix xinput1_4.dll Error on Windows 7

This workaround does not add native xinput1_4.dll functionality. It simply tricks the application into detecting a compatible DLL.

Step 1. First, navigate to C:\Windows\System32 and locate the file xinput1_3.dll. Copy this file to your desktop and rename the copied file to xinput1_4.dll.

Step 2. Once renamed, move it back into the System32 folder.

Step 3. Repeat the same procedure in C:\Windows\SysWOW64. Locate xinput1_3.dll, copy it to your desktop, rename it to xinput1_4.dll.

Step 4. Move it back into the SysWOW64 folder. Now, your game should be able to bypass the xinput1_4.dll error and launch successfully on Windows 7.

Additional Tips to Fix xinput1_4.dll Error

• This method only works for games that can function with xinput1_3.dll. Some newer games may still require full DirectX 12 support.

• If you encounter further DLL errors, consider using a DLL repair tool like Auto DLL Fixer, which can automatically detect and fix missing or corrupted DLL files.

• Always back up your system before manually replacing DLL files to avoid unintended issues.

Conclusion

The xinput1_4.dll Error (Error Code 126) is a common obstacle for Windows 7 users running newer games, but it can usually be resolved with a careful workaround. By renaming and replacing xinput1_3.dll, or by using automated tools like Auto DLL Fixer, you can bypass the error and enjoy your games on older systems.
