Error 0xc00007b means Windows could not load a required application component correctly. Causes can include damaged system files, missing official runtimes, architecture conflicts or an incomplete installation. Never copy individual DLLs from download sites into the game folder.
Safe order
- Install Windows updates and the graphics driver from the manufacturer's official tool, then restart.
- Run Riot Client's built-in repair.
- Use Windows' official system-file checking tools in an elevated Command Prompt and let them finish.
- Repair or reinstall Microsoft's official Visual C++ runtimes for your system architecture.
- If needed, reinstall Riot Client and LoL from the official source.
Avoid DLL sites, one-click fixers and random registry edits. On a managed PC, ask the administrator. See our LoL guides.
