• Select "Run as Administrator".

If the game launches, make this permanent:

• Right-click the shortcut > Properties > Compatibility tab > Check "Run as Administrator" > Apply.

2. Close Background Apps and Overlays

Third-party apps like Discord, MSI Afterburner, or Steam overlays can conflict with LoL.

• End tasks for: Discord; Razer Synapse; Nvidia GeForce Experience/ShadowPlay; Any screen-recording tools (OBS, XSplit).
• Relaunch LoL.

3. Repair Game Files via Hextech Repair Tool

• Run the tool and select "League of Legends".
• Click "Start Scan" and follow prompts to repair issues.

4. Update Graphics Drivers

Outdated GPU drivers are a common cause of game startup failures.

Open GeForce Experience > Drivers tab > Check for Updates.

Install the latest driver and restart your PC.

• AMD Users:

Open Radeon Software > Updates section.

Download and install the recommended driver.

5. Disable Antivirus and Firewall Temporarily

Security software might mistakenly flag LoL as a threat.

• Windows Security: Go to Virus & Threat Protection > Manage Settings > Turn off Real-Time Protection.

• Attempt to launch LoL. If successful, whitelist LoL in your antivirus: Add LeagueClient.exe, League of Legends.exe, and the Riot Games folder to exclusions.

6. Perform a Clean Reinstall of LoL

If all else fails, a fresh install eliminates deep-seated issues.

Uninstall LoL via Control Panel > Programs.

Manually delete leftover files:
