How can I completely uninstall Norton 360 and Epic Games Launcher on Windows 11?

If the uninstallers still fail, try restarting Windows and running the removal process again from an administrator account. Norton’s dedicated cleanup utility is the better option for a broken installation; manually deleting its files or changing system settings could cause additional problems.

First check that your Windows account has administrator privileges. A restricted or standard account may not be allowed to uninstall some programs. For Norton, use its official Norton Remove and Reinstall tool if the regular Windows uninstall process is failing. Epic Games Launcher should normally uninstall through Settings > Apps > Installed apps, or through the classic Programs and Features panel. Avoid simply deleting the program folders, since that can leave services and registry entries behind.
