I have bought games outside of Steam, for example Fable 3, but I want to install some mods for it from the Steam Workshop. I would prefer to use Steam Workshop to install mods, as I don't trust my abilities to install them manually. Plus it's a lot easier to manage from the Steam Workshop.
What I tried so far:
- I have installed and logged into Steam,
- Added Fable as a 'Non-Steam-game'
- Opened up workshop and subscribed to a mod,
- then opened the game.
But nothing happened, i.e, No mod was installed when I ran the game.
Obviously Steam isn't picking up the copy of Fable 3 from the 'Non-steam-game' shortcut. How do I tell Steam that I own a copy of Fable 3? Do I need to enter the game's product key into Steam to enable it installing the mods for me?
