⚠️ What Causes "Not Found" DLL Errors in League of Legends?

DLL files (Dynamic Link Libraries) are like the unsung heroes powering your game—handling graphics, audio, and more. When League of Legends screams "Not Found" (e.g., VCRUNTIME140.dll or MSVCP140.dll missing), it's because these files are corrupted, outdated, or deleted. Common culprits?:

  • 🔥 Incomplete game updates or botched installs.
  • 🦠 Malware or antivirus overkill deleting files.
  • 💻 Outdated Windows or Visual C++ libraries.
  • 🎮 Faulty graphics drivers clashing with the client.

These errors hit hard during launch or mid-game, especially after big patches. But with our fixes, you'll be back farming minions in no time! 💪

📋 Common League of Legends "Not Found" DLL Errors & Quick Diagnosis

Spot your enemy? Here's a handy table of the most notorious ones:

DLL File Error Message Quick Cause

MSVCP140.dll "MSVCP140.dll not found from LeagueClient.exe" Missing C++ runtime libraries
d3dcompiler_47.dll "d3dcompiler_47.dll is missing" DirectX or graphics driver issue

  2. Delete leftovers: C:\Riot Games\League of Legends and %localappdata%\Riot Games.
