I have a CD key, how do I add it to GOG?
I bought the game itself a long time ago, there are no disks left, but the license keys are saved.
I have the keys: SWAT 4: Gold Edition / The Stetchkov Syndicate.

Why would you need to? GoG version is DRM free.

If you mean you never bought the game on then your CD key doesn't entitle you to a free game on the platform, sorry.
