Q: Is uplay-r1-loader64.dll a virus? A: No, it is an official Ubisoft file. However, because it "injects" code into the game, some aggressive antivirus programs treat it like a crack. This is a false positive.

Q: I pirated the game. Can I fix this? A: This article is for legal copies. Cracked versions often have custom DLLs. If you have a legitimate copy but installed a crack mod, the DLL is intentionally replaced. Verify your game files to restore the original Ubisoft DLL.

  3. Restart your PC.

2. Run as Administrator

Right-click on your Far Cry 4 shortcut > Properties > Compatibility > Check "Run this program as an administrator." Do the same for Ubisoft Connect.exe and Steam.exe. This gives the launchers permission to write the DLL file into protected system folders.
