Your Riot Client may not open due to a permissions issue. If it lacks the necessary permissions to access specific system assets, the client won’t launch. Therefore, running it as an administrator may fix the issue.

Try running Riot Client in compatibility mode for XP, Windows 7, and Windows 8. Many users have found that running Riot Client in compatibility mode was the most effective way to fix Riot Client not opening.
