Applies to: Far Cry 4 (Steam, Epic Games, or standalone retail versions)

| Action | Status | |--------|--------| | Check antivirus quarantine | ☐ | | Add game folder as exclusion | ☐ | | Copy correct crack DLL into bin\ | ☐ | | Verify filename (hyphen vs underscore) | ☐ | | Or verify legitimate game files | ☐ |

If none of the above works, the crack you have is incomplete or incompatible with your Windows version (e.g., Windows 10 22H2 or Windows 11). Consider finding an updated crack from a trusted scene group.

Windows' Controlled Folder Access (part of Ransomware Protection) can block games from loading DLLs.

Do not use cracked DLLs. Instead:

Uplay/Ubisoft Connect:

Steam:

Epic:

After verification, the legit launcher (UplayPC.dll or UbisoftConnect.dll) will be restored – not the crack file.

If you had a cracked version before and now own it legally, uninstall completely, delete leftover folders, then reinstall through the legit store.

Q: I found uplay-r1-loader64.dll in my folder, but the error persists. Why? A: The file may be corrupted, or a permission issue is blocking it. Try deleting the file manually, then run Method 2 (Verify Integrity) to download a fresh copy.

Q: Does this error occur on Windows 11? A: Yes, frequently. The solutions above work identically on Windows 10 and Windows 11.

Q: I don't have any antivirus besides Windows Defender. Why is this happening? A: Windows Defender has become increasingly aggressive. Follow Method 1 to check its quarantine history and add an exclusion.

Q: Can I just copy the file from a friend's computer? A: Technically yes, but it is unwise due to potential version mismatches (Steam vs. Epic vs. Retail). Always use the launcher's verification tool instead.

The "uplay-r1-loader64.dll missing" error in typically happens because your antivirus software has mistakenly flagged and quarantined the file, or the Ubisoft Connect (formerly Uplay) installation is corrupted. Recommended Fixes

Check Antivirus Quarantine: Open your antivirus software and look for the uplay-r1-loader64.dll file in the "Quarantine" or "Virus Vault" section. If found, restore the file and add it to your antivirus exclusion list to prevent it from being deleted again. Verify Game Files:

On Ubisoft Connect: Go to "Games," select Far Cry 4, go to "Properties," and click Verify files.

On Steam: Right-click Far Cry 4 in your Library, select "Properties" > "Installed Files" > Verify integrity of game files.

Reinstall Ubisoft Connect: Sometimes the launcher's own core files are the issue. Download the latest version from the Ubisoft Connect website and install it over your current version to repair missing DLLs.

Manually Restore the DLL: If verification fails, you can manually replace the file in the game's folder (usually Far Cry 4\bin). However, ensure you only download DLLs from reputable sources, as third-party DLL sites can carry security risks.
