I Far Cry 4 Dual Core Fix Extreme Injector Windows 10 Repack ((full)) May 2026
Far Cry 4
Far Cry 4 is an open-world first-person shooter developed by Ubisoft. It was released in 2014 and can be quite demanding, even for modern hardware.
Part 1: Why Far Cry 4 Hates Dual Core CPUs
To understand the fix, you need the technical background.
- The Culprit: The file
FC64.dll(orFC64_d3d11.dllin some versions) contains hardcoded CPU feature checks. If the CPU doesn’t report SSE 4.1 support, the game triggers a silentEXCEPTION_ILLEGAL_INSTRUCTION. - The Myth: Many users think the game requires four physical cores. That’s false. The game runs fine on a dual-core with Hyper-Threading (e.g., Core i3-4130) because those chips have SSE 4.1. The problem is older dual-cores without SSE 4.1 (e.g., Pentium E5400, Core 2 Duo, early Atoms).
The official patch (v1.10) did NOT fix this. Ubisoft never addressed dual-core support.
Conclusion
Thanks to the modding community, Far Cry 4 is playable even on aging dual-core hardware. Using Extreme Injector to apply the dual-core patch remains the most reliable method for Windows 10 users running repack
on a dual-core CPU, you must use a third-party tool like Extreme Injector to bypass the game's check for a quad-core processor. Without this, the game usually hangs on a black screen at launch. 🛠️ Preparation
Locate the Bin Folder: Open your Far Cry 4 installation directory (e.g., C:\Games\Far Cry 4\bin). i far cry 4 dual core fix extreme injector windows 10 repack
Required Files: Ensure you have the following in that bin folder: Extreme Injector v3.x.exe. dualcore.dll. EasyHook64.dll (often bundled with the fix).
Antivirus Exception: Add the bin folder or the injector specifically as an exception. Antivirus programs often flag injectors as "riskware". 🚀 Standard Method (Auto-Inject)
This is the most reliable method for Windows 10 repack versions.
Run as Administrator: Right-click Extreme Injector and select Run as administrator.
Configure Settings: Click the Settings button and ensure Auto-Inject is checked. Add the Fix: Click Add DLL and select dualcore.dll. In the Process Name box, type FarCry4.exe exactly. Far Cry 4 Far Cry 4 is an
Start the Game: Keep the injector open and launch the game. It should automatically detect the process and inject the DLL. 🕒 Manual Method (If Auto-Inject Fails)
If you still see a black screen, use this manual timing method.
Open Injector: Run it as administrator and uncheck Auto-Inject in Settings. Launch Game: Start Far Cry 4.
Inject Manually: As soon as the first loading splash screen appears, quickly switch back to the injector and click Inject.
Confirm: You may need to click "OK" on several confirmation pop-ups for the injection to take hold. 💡 Troubleshooting for Windows 10 The Culprit: The file FC64

Method B: Extreme Injector (Legacy & Risky)
Why would you use Extreme Injector?
Some older mods (trainers, FOV changers, or memory patches) required dynamic injection post-launch. The search query includes "extreme injector" because a 2015-2016 workaround involved injecting a custom DLL (FCDualCoreFix.dll) after the game launched but before the SSE 4.1 check.
The Process (Now Obsolete & Dangerous):
- Download Extreme Injector v3.7.3 (from unknowncheats.me – note: this is a known malware vector).
- Launch the injector (Windows Defender will flag it – that’s a red flag).
- Set injection method to
Manual MaporLdrLoadDll. - Locate
FarCry4.exeprocess. - Inject the legacy
FC_fix.dll. - If successful, the game proceeds.
Why you should AVOID this in 2023:
- Extreme Injector is now flagged by 50+ antivirus engines. Many "repack" versions bundle cryptominers.
- Windows 10’s Core Isolation (HVCI) blocks unsigned DLL injection.
- The simple patch (Method A) makes injectors irrelevant.
If you still see "extreme injector" in repack names: This usually means the repacker bundled the injector as a fallback for users who couldn’t get the simple DLL patch to work. It is not required for modern dual-core fixes.
Part 3: Prerequisites – What You Need Before Starting
Before you download any tools, ensure your Windows 10 system is ready.
- The Right Version of Far Cry 4: This fix works best with Version 1.10.0 (the final update). If your repack is v1.9.0 or earlier, update it.
- Visual C++ Redistributables: Install everything from 2010 to 2022 (x86 and x64). The injector relies on these.
- DirectX Runtime: Run the DXSETUP.exe found in the game’s
_Redistfolder. - Windows 10 Version: Works on 1809 to 22H2 and Windows 11 (via compatibility mode).
- Antivirus Realities: Windows Defender will flag Extreme Injector and the fix DLL as "HackTool:Win32/Injector" or "Win32/PotentiallyUnwanted". This is a false positive. The tool modifies a running process, which is behaviorally similar to malware, but for legitimate purpose. You must add an exclusion folder.
Error 2: Game Launches but Keyboard/Mouse Freezes After Injection
- Cause: The dual-core fix DLL sometimes conflicts with input hooking.
- Fix: In Extreme Injector settings, enable "Stealth Injection" and disable "Create Backup". Reboot and try again.
Part 8: Ethical & Security Warnings (Read Carefully)
- Repack Legality: Repacks are pirated software. This guide is for educational and archival purposes. The dual-core fix works on legitimate Steam/Uplay versions too, but those versions have stricter anti-tamper, making injection harder.
- Account Safety: Never run Extreme Injector while connected to a game with anti-cheat (EAC, BattlEye). It will ban you. Close the injector after Far Cry 4 is running.
- Backup Your Saves: Corrupted injector settings can rarely corrupt your save file located in
Documents\My Games\Far Cry 4. Back upsavegames\folder first. - SHA256 Checksums: If you download Extreme Injector from an untrusted source, it may contain a RAT. Always check the original developer’s signature (WeiChu Chen / discord). The legitimate size is ~1.2MB for v3.7.2. If it’s 500KB, delete it.
Part 5: Known Conflicts on Windows 10
Even with the dual-core fix applied, Windows 10 introduces its own problems.
