I don't know if anyone had this problem too, but no matter how many times I download the game I don't have "game.exe" file like it was on other games. (Im on windows) All I can see is just "game.exe.exe" which, indeed does work but horibbly. None of the pictures will show up, + the audio just straight up dissapears, there's only a black screen with text for the whole game (+ it takes YEAAARS to load anything?? Its barely playable.) I have the other games too, the same happened with cold front but the rest does have "game.exe" and it works just fine. I even tried to download it on my phone to maybe send it over to my pc later, but the "game.exe" is still gone. My friend tried too, the same effect. I'd appreciate any help I can get, I love both of these games and I would love to get the full experience by playing them myself ;)
I haven't faced this issue but I'm going to assume that maybe it has to do with your computer? It could be that for some reason your Windows Defender considers it a false positive and deletes it from the folder. I suggest adding it as an excluded software from having it checked. I do believe that your computer is the cause.
