This error can occur if Windows is not up-to-date. Try downloading the Windows Hotfix: http://support.microsoft.com/kb/2922790 and then restart Windows for changes to take effect.
If the Windows Update does not help, then the issue is likely to be caused by anti-virus software falsely detecting EAC protected game as malicious software.
We're in contact with several anti-virus companies who have already whitelisted EAC, but if yours hasn't, you can find ways to add an exception for your game from here.
This error appears when the system is unable to load any kernel-mode driver. This would indicate a system level corruption, which unfortunately is most often irreversible without re-installing Windows. Possible causes are a rootkit virus infecting the system, blocking any other non-boot-time driver to be loaded, or a corrupted old anti-virus installation that failed to uninstall cleanly. In either case, we strongly recommend you to reinstall Windows.
This error is occurring because there is already an instance of EAC protected game running. Open task manager and close the game processes and also EasyAntiCheat.exe. Alternatively, restarting your computer will also resolve this issue.
