I'm on GOG... which, possibly tellingly, has no setup instructions yet.

I wish Larian would just put the toolkit up on their website. Steam had serious issues distributing this at first from what I've heard (many people couldn't see the data initially, though a manual request to download via Steam console worked) and it STILL isn't working for GOG.

Blarg.

Hopefully, someone from Larian sees this fixes the GOG Divinity Engine package.
