"The directory is missing a launcher profile. Please run the minecraft launcher first"

[jax7898]

Hi there. I recently installed forge (1.12.2) to play some MC mods. Since I'm new, I've been following a step-to-step guide on how to install forge and download mods, and have hit a roadblock because I can't seem to find out why it won't work. Yes, I have played minecraft previously to this, and have my own profile. Bare in mind that this profile is a microsoft account (whether or not that has anything to do with it?) Either way, any help would be greatly appreciated. Thanks

1.12 is no longer supported on this forum.
Please update to a modern version of Minecraft to receive support.
