Hello, Febrifacient! By any chance did the error mention a file named irrKlang.dll? Commonly when you install a program, a desktop icon called a shortcut will pop up, giving you quick access to the program without having to search through your files. When people accidentally move the entire game's .exe out of the Feralheart folder instead of making a shortcut, this error will pop up because that file is game's .exe, and not a shortcut targeting the file. To fix this issue, simply move the Feralheart.exe file back into \Feralheart. To create a shortcut of Feralheart targeting that .exe, right-click the Feralheart.exe file, click "copy," go to your desktop, right-click and select "paste as shortcut." Once you have created a shortcut to the Feralheart.exe file, you can readily start the game up without searching for the game through your computer files.
