It used to be that installing FAF was as simple as running the installer. Now it's not.
I have Supreme Commander and Forged Alliance both installed. But now installing FAF it tells me that I have to have either game installed via Steam. Except I can't find the box with the CD key, and the one retrieved from the registry isn't recognised by Steam.
Importing the game into Steam as an existing game also doesn't work.
So now to install FAF I have to buy Supreme Commander again? That's not very good. It's not particularly expensive, but I have a pathalogical dislike of buying things that I already own.
Any advice?
