Re: Sims 4 legacy edition folder isn't there.
@Lunarmint20 Thank you. If you played the game there will be a user folder somewhere. If you saved once there will be a save file in it.
Sorry for getting back to this, but did you follow the detailed descriptions in the link above, of how to find your user files? If you did not save your play, make a new save and use Save As under a recognizable name, like Test. Then look in the Main Menu, like shown in the pictures in the blog post, for the path to the save. What does it say?
More silly questions, thanks for bearing with me :D
Is your old The Sims 4 folder in Documents>Electronic Arts?
From within the save you just started, can you access the Gallery?
I am only guessing here, and I don't have the Legacy Edition; but there is no online access with it, and if you can access the gallery, maybe the installation went wrong and you are still using the regular version.
