Key takeaways
- League of Legends compatibility mode is disabled from the executable’s Windows Properties > Compatibility tab.
- Riot’s commonly referenced default executable path is
C:\Riot Games\League of Legends\Game\League of Legends.exe. - Changing a desktop shortcut may not change the compatibility setting stored on the actual
League of Legends.exefile. - If compatibility mode is already disabled, check Windows support, graphics drivers, antivirus or firewall exceptions, and other Riot launch components.
- Do not casually enable “Run this program as an administrator” on the individual game executable; Riot distinguishes game permissions from Riot Client permissions.
How to remove compatibility mode in League of Legends?
Removing compatibility mode requires clearing one Windows setting on the League executable. Riot’s support instructions say to open the game file’s Properties, select Compatibility, disable the compatibility-mode option, and apply the change.

Which League of Legends file should you change?
Change the setting on the actual game executable first: League of Legends.exe inside the Game folder. Riot’s commonly referenced default path is C:\Riot Games\League of Legends\Game\League of Legends.exe; if League was installed elsewhere, search the installation folder for the same filename. Riot’s launch troubleshooting guidance also distinguishes the game executable from the launcher and other Riot components.

A desktop shortcut can have its own compatibility-related settings. For that reason, check both the shortcut and the underlying executable when League continues to report compatibility problems. The executable in the Game folder is the more important location for this specific fix.
What are the exact steps to disable compatibility mode?
- Close League of Legends and exit the Riot Client.
- Open the League installation folder, or locate the League shortcut on the desktop.
- Right-click
League of Legends.exeor the relevant shortcut and select Properties. - Open the Compatibility tab.
- Under Compatibility mode, clear Run this program in compatibility mode for….
- Select Apply, then select OK.
- Open the Riot Client again and launch League of Legends.
Riot’s official procedural wording is “Desactiva el modo de compatibilidad,” meaning “Disable compatibility mode.” The instruction appears in Riot’s launch troubleshooting material alongside the path and executable checks. Read Riot’s official launch guidance.
What if compatibility mode is already disabled?
If the compatibility checkbox is already clear and League still will not launch, compatibility mode is not the remaining cause identified by that setting. Continue with the next launch checks in a controlled order rather than changing unrelated Windows or BIOS settings.

| Check | When to use it | What to inspect | Risk and scope |
|---|---|---|---|
| Compatibility setting | First, when Windows or League reports compatibility mode | League of Legends.exe and its shortcut |
Low risk and easily reversible |
| Windows support | When the message says the operating system is unsupported | Whether the installed Windows version meets Riot’s current requirements | Broader system check; do not assume a version is supported without current Riot documentation |
| Graphics driver | When launch or post-champion-select failures continue | Install the current driver supplied for the graphics hardware | System-level change; follow the manufacturer’s normal update process |
| Antivirus or firewall | When security software may be blocking Riot or League processes | Riot’s documented executable exceptions and security logs | Security-sensitive; use only the required exceptions |
Riot’s unsupported-operating-system guidance recommends checking the supported Windows environment, while its launch-crash material includes graphics-driver and security-software troubleshooting. See Riot’s unsupported-operating-system guidance and its launch-failure checks.
Which Riot files may matter after the game executable?
If checking League of Legends.exe does not resolve the launch failure, Riot’s troubleshooting material commonly refers to these files:
C:\Riot Games\League of Legends\LeagueClient.exeC:\Riot Games\League of Legends\LeagueClientUx.exeC:\Riot Games\League of Legends\LeagueClientUxRenderer.exeC:\Riot Games\League of Legends\Game\League of Legends.exeC:\Riot Games\Riot Client\RiotClientServices.exe- Riot Vanguard executables in the Riot Vanguard installation directory
Check these components only as follow-up troubleshooting. The direct answer to removing League compatibility mode remains the Compatibility tab on the relevant executable’s Properties window. Riot’s executable and antivirus-exception guidance lists the components involved in certain client crashes.

Should you run League of Legends.exe as administrator?
No blanket administrator change is required to remove compatibility mode. Riot’s permissions guidance distinguishes the Riot Client from the individual game executable and warns that changing permissions on individual game executables can create errors. Leave administrator settings unchanged unless Riot’s current instructions for your specific problem explicitly require a different step. Review Riot’s permissions guidance.
What should you avoid changing?
Compatibility mode is a Windows executable setting. Do not confuse it with fullscreen optimizations, Windows Exploit Protection, virtualization-based security, BIOS virtualization, or other system settings. None of those settings is part of the direct procedure supplied for removing League of Legends compatibility mode.
Third-party repair software is also unnecessary for the documented fix. The Windows checkbox change is free, reversible, and should be completed before considering any broader troubleshooting tool.
