, you generally need to restore the file from your antivirus quarantine or manually replace it from your game's internal backup folders. This error is usually a "false positive" where Windows Defender or other antivirus software flags the file as a threat and blocks it. 1. Restore the File from Windows Security
Most of the time, the file isn't actually "missing"—it's just being held hostage by your antivirus. Open Windows Security and go to Virus & threat protection. Click on Protection history.
Look for a "Severe" threat or blocked item that mentions uplay_r1_loader64.dll. Click Actions and select Restore.
Crucial Step: Immediately add your Assassin's Creed Unity folder to the "Exclusions" list in your antivirus settings so it doesn't delete the file again the next time you launch the game. 2. Use the Built-in Backup (NoDVD Folder)
If you are using a specific version of the game (like a repack), the installer often leaves a backup of the necessary DLLs inside the game directory. Go to your main Assassin's Creed Unity installation folder. Look for a folder named NoDVD or SKIDROW. Inside, you should find a copy of uplay_r1_loader64.dll. For Ubisoft Connect:
Copy it and Paste it directly into the main game folder where the .exe is located. 3. Verify Game Files (Official Versions)
If you own the game on Steam or Ubisoft Connect, use the built-in repair tool to download the correct official file.

Ubisoft Connect: Go to the game's page > Properties > Verify files. 4. Manual Download (Last Resort)
If the file is completely gone and you don't have a backup folder, you can download it from a repository like DLL-files.com.
Warning: Only download from reputable sources. Once downloaded, extract the .dll and paste it into the game's main installation directory.
Common Pitfall: If you just replace the file without adding a "Folder Exclusion" in your antivirus, the game might crash or the file will disappear again within seconds of you trying to play. If you're still having trouble, let me know: Are you using the Steam, Ubisoft, or a repack version? What antivirus are you running?
Does the error say the file is "missing" or is it a "procedure entry point" error?
