Does the Game Crash when you start it?
If the game crashes upon starting it, this is most likely due to that it displays the window in a font that is too big for your your desktop. You can solve this by creating a shortcut to the game (right-click and select “create shortcut”), on the shortcut you can then adjust the font size to a smaller one by right-clicking the shortcut, select “properties” and then select the “font” tab and do your adjustments.
Thanks to TyreForHyre for this workaround!
