I know this is likely a dumb question and I'm probably missing something easy...but I bought the DLCs during the GOG sale and can't figure out how to install them from the GOG Galaxy Client.

I've never had an issue with GOG Galaxy Client and I have no complaints about it...any assistance in getting these installed, would be greatly appreciated.

By default it should install automatically when opening Galaxy. Otherwise the DLC count next to where the the game's patch version is displayed takes you to your DLC content. You can check in there, if any of the boxes are ticked.

It was strange, the option to click them wasn't there. Long story short, I ended up figuring it out..but it took a while. Had to close and re-open a few times, then around to finally get them to install.
