Installer and keyboard binding is defect

Keyboard rebinding in this game do not work in a persistent manner (for me at least). I am left-handed. So I do change movement from WASD to arrow keys, and so on. But as soon as the game is started next time. All settings is reset back to default. Now this true for any change to Keyboard rebinding. So you have to reapply all keybindings every time the game is started. Consequently I never got far into playing much of the games content or any of its story (if it exist). This speaks of a game that never was completed.
