Invalid subnautica directory error

[Arthplum]

Describe the issue

Hello,
I've just encountered an issue while trying to locate the subnautica file (from steamunlocked), where an 'invalid subnautica directory' message appears.
Do you know what to do ? Maybe i should download it from an other site ?

Which exact folder are you choosing? It's the one that contains all the game files, right?
Regarding the version, you need to use a fairly recent version. Depending on where you downloaded it, it might not be compatible with the launcher. Which version are you using? You can see it in the game's main menu, at the top right.
