The League of Legends installation may fail if you don't have administrator access to your computer, or if something is interfering with your network connection.
If your version of Windows needs updating, you may have trouble installing League. Just search for “Windows Update” in your Start menu and click “Check for updates”.
Run installation as administrator
First, make sure you've downloaded the game from the League site. Then locate the file, right-click the installer, and select "Run as Administrator".
Temporarily disable your firewall
If you've installed a third-party firewall, try disabling them before installing or starting a patch. Windows comes with its own firewall, which you can disable by following these steps:
- Click on Start
- Click on Control Panel
- Click on System and Security
- Click on Windows Firewall
- Click on Turn Windows Firewall on or off (You may be prompted to enter the Admin password at this step)
- Under each network location, select the "Turn off Windows Firewall" option
