If you are prompted by the launcher to install Service Pack 1 and already have it installed or are on a newer version of Windows, check the launcher's application compatibility mode settings. These settings make programs think that they are running an older version of Windows, and should always be disabled for the Epic Games launcher.
To check the Windows compatibility mode options, please do the following:
- Right click the Epic Games Launcher desktop shortcut.
- Select Properties.
- Select the Compatibility tab.
- Make sure that the Run this program in compatibility mode option is unchecked.
- If you absolutely require compatibility mode, make sure that the selected version of Windows is Windows 7 SP1 or newer.
