My GD folder (SteamGames/steamapps/common/Grim Dawn) is 6.81 GB. This suggests to me you've had, for some reason, an incomplete download. (My GD .exe is 3,217 KB, if that is more specifically what you are referring to.) If you download from Crate or Steam, there should be no issue. However, if you are sure you have a clean copy, I would recommend adding the game / the installer to your AV's white list or turning it off entirely for the short period needed to install it, if that's what you said you were trying to run it.My AV keeps deleting the 1.0.7 version whenever I try and run it, saying that it is infected with Win32:Malware-gen and when comparing the file sizes with 220.127.116.11, v1.0.7 is only 888kb and 18.104.22.168 was 4,669kb. Any idea?
