My question is now, how is it with playing in those places, do they just need a normal license?
Academic institutions can apply for a 30% academic discount, but otherwise, yes, licenses work the same for them.

Can they do it without, if I send them the file? Or how is that?
Any Isadora file can be run without an Isadora license in demo mode; the only limitation is that they won't be able to save. That being the case, the answer to your question depends on whether your file is built in such a way that saving changes is important. For example, if you've got Controls in the Control Panel that let them tweak various parameters like the volume of Sound Players or the intensity of Projector actors, if they make adjustments like that without a license, they won't be able to save the changes, so those changes will be lost and the file will return to its original state when they close it. The end result of that situation would be that, without a license, they'd need to make the same changes again every time they re-open the file. If your file just runs as is without any way to adjust values, then yes, they could do everything they need without a an Isadora license.
