2. Download the correct version for your system:
   • vc_redist_x64.exe for 64-bit Windows
   • (If you use 32-bit apps) also optionally install vc_redist_x86.exe.
3. Run the installer → choose Repair if it’s already installed, or fresh install if not.
4. Reboot your PC.
5. Launch League of Legends — the error should be gone.

2. Copy the DLL to the Game Folder (As a Temporary Workaround)

If reinstalling doesn’t help or you need a quick fix:

• Download a safe copy of VCRUNTIME140_1.DLL from a trusted DLL repository (make sure source is reputable).
• Copy the DLL file to the game’s installation directory — usually something like: C:\Riot Games\League of Legends
• Optionally also paste into: C:\Windows\System32
• Then run the game again.

⚠️ This is a workaround — the recommended method is the official redistributable.

3. Update Windows & Ensure System Files Are Intact

Sometimes Windows updates or file corruption cause DLL issues.

• Open Windows Update → install all pending updates and reboot.
• Open Command Prompt (Admin) and run: sfc /scannow This scans and repairs corrupted system files.
• After scan completes, restart PC and retry launching the game.

This ensures that Windows system components (including runtime libraries) are intact and up-to-date.

4. Repair or Reinstall League of Legends

If the DLL is fine but game still crashes:

• Open the game launcher → Settings → Repair / Reinstall (if supported).
• Or remove the game entirely → download fresh installer from official source → reinstall.

This resolves issues where game-specific files are corrupted or missing.

5. Check Antivirus / Security Software & Exclusions

Sometimes security tools block or delete DLL files (mistaking them for threats).

• Check your antivirus quarantine / logs — if VCRUNTIME140_1.DLL is flagged, restore it and mark it as safe.
• Add the game folder path to antivirus exceptions — to prevent future deletions.
• Turn off “real-time scanning” temporarily while installing redistributables or the game.

This ensures legitimate runtime libraries remain intact.
