What do I have to do in Minecraft so that the game I open via LAN (Hamachi) can also join my colleague with the cracked version?

The other colleague who does not have the cracked version can join. The colleague with the cracked version always displays an error message about the session.

This is not possible over LAN. Runs only with stand-alone server.

Uh, but with a colleague it went.

Standalone server is better either way.

LAN is just a quick fix, if you really do not feel like configuring anything, and if you use Hamachi anyway, that's nonsense.

This is not possible over LAN.

You have to create a normal server, because only then you can set in the server options (which are not available on LAN servers) that cracked accounts may join. With LAN servers one has no possibility to change the server options. Except maybe with this https://minecraft.curseforge.com/...es-for-lan, but since I have no experience with it. If you are too complicated Mods:

Just download a https://minecraft.net/...ad/server/ (there are good tutorials on YouTube and https://minecraft-de.gamepedia.com/...er_starten, how to set it up) and drag your map up there. Then go to server.properties and swap "online-mode = true" with "online-mode = false". Then start the server, and you're done. Now your buddy can join.

Many Thanks:-)

No problem.
