If you’ve recently installed the UNCHARTED: Legacy of Thieves Collection on your PC, you might have noticed a file named tll.exe in your game directory. While it might look like a random system file, it’s actually the heart of your treasure-hunting experience. The Role of tll.exe
In the Legacy of Thieves Collection, the game is split into two main executables: u4.exe: Launches Uncharted 4: A Thief's End. tll.exe: Launches Uncharted: The Lost Legacy.
The name "TLL" is simply an abbreviation for The Lost Legacy. When you select the game from your Steam or Epic Games library, your computer calls this file to start Chloe Frazer and Nadine Ross’s adventure in India. What about tll-l.exe?
You might also see a variation called tll-l.exe. This is a "fallback" version of the executable designed specifically for older CPUs that do not support AVX2 instructions. High-performance PC? Stick to tll.exe.
Older hardware? Use tll-l.exe for better stability and compatibility. 💡 Troubleshooting Common Issues
Sometimes, tll.exe can cause a headache. Here are the most common fixes for players: 1. "tll.exe Not Found"
If you get an error saying the file is missing, it’s often because your Antivirus or Windows Defender flagged it as a "false positive" and quarantined it.
The Fix: Check your antivirus protection history and "Restore" the file. Adding the game folder to your Exclusions list can prevent this from happening again. 2. Game Won't Launch If clicking the file does nothing:
Run as Admin: Right-click tll.exe > Properties > Compatibility > Check "Run this program as an administrator".
Disable Optimizations: Some AMD users find success by going to Windows Graphics Settings and disabling "Optimizations for windowed games" for this specific file. 3. File Verification
If the file is corrupted, you don't need to reinstall the whole game. Use the "Verify Integrity of Game Files" option in Steam or the Epic Games Launcher to repair just the missing or broken tll.exe. 🛡️ Is tll.exe Safe?
Yes, as long as it is located within your official game installation folder (usually under SteamLibrary\steamapps\common\Uncharted Legacy of Thieves Collection).
