When I install this game it does not show up in GOG games, in control panel, no icon.What can I do to get it to show an icon?

It's a DLC for Season 1. Just selected it as an episode from the Season 1 episode menu.

I know. I have the other two, too.

OK. What exactly are you trying to do?

Play 400 days.

Run Season 1, select 400 days from in game menu. At least I think that's the way to do it.

It doesn't show up in my list of games in GOG Galaxy, either.

That's because it's a DLC for the Walking Dead Season 1. DLCs don't have separate entries on GOG.

It's not supposed to. It's a DLC for Walking Dead Season 1.

It DOES NOT have it's own EXE file.

Open Walking Dead Season 1, and scroll through the Episodes, it should be selectable there.

I just did. It shows it's installed but when I click on it does nothing.

OK, so it shows up in the episodes, but doesn't play when you select that episode?

Weird, maybe you have to finish Season 1 before playing it? (Not sure as I haven't played in a while)

I'd think it would have to be played first. It's colored red(the box that has to be clicked). Does that mean anything?

If you have already finished Season 1, load up a save game then try starting 400 days.

Okay, I'll give it a try. If I need more help I'll come back. Thanks everyone!
