Return of Reckoning

If you use Windows Defender, just set the game folder as an exception and it will update and run just fine. That's what I did and I've had no problems since.

Windows Defender kept saying that there was a Trojan in the file and would kill the program, I scanned it multiple times and figured it out it's a false positive. I set the game folder as an exception in WinDef and it updated just fine the next time I launched it. Hope that helps you too.
