Feral Heart

I have just recently started playing Feralheart, and I removed the game using un-installer a long while ago, but I want to play again, so i tried downloading the installer today, but it came up with a warning saying "Setup files are corrupted, please obtain a new copy of the program" I have looked up all sort of ways, but don't know what to do, please help!
(I have checked on my laptop, and there is no evidence that the game is still on there. I think it might be the installer, but don't know.....)
