Not because I know where this is at hand, but you can really sort this out easily by.
Downloading a FH installer or already using one you have.
Install the game to another location on your computer Not C:\FeralHeart But instead maybe make a new folder like this.
C:\FeralHeartstuff\FeralHeart
C:\Justanothergame\FeralHeart
Or even just place it on another harddrive and run the install. Once you are done you can just fetch whatever it is that you need and then remove the extra game that you installed. It's both easier for you and everyone else and as long as you choose another path for the game to be installed, it will never interfere with the other game that you originally had in C:\FeralHeart
