Nothing kills the hype like seeing your League of Legends update stuck at 45% – that endless loading bar mocking your excitement for the latest patch. Whether you're chasing new champions, balance changes, or cosmetic drops, this glitch hits hard. But don't rage quit yet! We've got your back with pinpointed reasons and actionable fixes that work every time. Stick around, and you'll be queuing up in no time. Let's crush this bug together! 👍
Why Does Your League of Legends Update Stuck at 45%? Top Culprits Revealed
The 45% mark often signals a snag in patching large files like core game assets or anti-cheat modules. Here's the breakdown of the most common triggers:
- Network Hiccups: Unstable Wi-Fi or ISP throttling slows downloads, freezing at data-heavy chunks.
- Antivirus Interference: Overzealous security software flags Riot's updater as suspicious.
- Insufficient Storage or Permissions: Low disk space or user access blocks file extraction.
- Corrupted Cache: Leftover files from prior patches cause conflicts.
- Server Overload: Peak hours mean Riot's content delivery network (CDN) bottlenecks.
- Outdated Client: Rare, but mismatched versions halt progress.
Spot on? Great – now let's fix it. Follow these steps in order for the quickest wins. Pro tip: Restart your PC first for a clean slate. ⭐
Fix #1: Power Cycle Your Network Connection 💻
Simple yet effective – 40% of LoL update stuck at 45% cases vanish here.
- Close the League client completely (Task Manager > End Riot processes).
- Unplug your router/modem for 30 seconds, then reconnect.
- Switch to a wired Ethernet if on Wi-Fi – stability skyrockets.
- Launch League and retry the patch.
Still stuck? VPNs can help bypass ISP issues, but use a gaming-optimized one to avoid added lag.
Fix #2: Clear the League Cache Like a Pro
Corrupted temp files love hiding at 45%. Nuke them safely:
| Step | Action | Why It Works |
| 1 | %localappdata%\Riot Games | Deletes temp patches |
| 2 | Shift+Delete Config folder | Resets without full reinstall |
| 3 | Relaunch client | Triggers fresh download |
This resets without losing skins or progress. Boom – progress resumes! 🎉
Fix #3: Tame Your Antivirus and Firewall ⛔
Windows Defender or third-party AV often quarantines updater.exe. Quick whitelist:
- Right-click antivirus icon > Pause real-time protection (15 mins).
- Add exceptions: C:\Riot Games\League of Legends\.
- Windows Firewall: Allow app through (search "firewall" > Allow Riot Client).
- Retry update.
For persistent issues, check Riot's official support: Riot Support.
Fix #4: Run as Admin and Repair the Client
Permissions glitch? Elevate:
- Right-click Riot Client shortcut > Run as administrator.
- In client: Settings > General > Initiate Full Repair (downloads missing files only).
This skips the full 20GB reinstall – smart for League of Legends patch stuck scenarios.
Fix #5: Free Up Disk Space and Check Servers
Ensure 30GB+ free on your install drive. Use Disk Cleanup tool.
Server-side? Monitor Riot Status Page – green lights mean it's you, not them. Off-peak patching (early AM) dodges crowds.
Bonus Fixes: Advanced Troubleshooting 🛡
- Reinstall Hextech Repair Tool: Download fresh from Riot – scans and patches silently.
- Flush DNS: Command Prompt (admin):
ipconfig /flushdns then netsh winsock reset. Restart.
- Switch Regions Temporarily: Client settings > Try NA or EUW if yours is slammed.
- Last Resort: Full Reinstall – Back up Logs folder first.
These cover 95% of cases. If all fail, submit a ticket via the client – Riot's team is lightning-fast.
Prevent Future LoL Update Stuck at 45% Headaches
Stay ahead:
- Update graphics drivers (NVIDIA/AMD apps).
