Set the language for the whole presentation

[JorisBK]

I don't manage to set the language of the whole presentation.

Is there a quick way to do that?

Best,

Do you mean translating from one language to another? No, PPT won't do that.

If you mean changing the language ID of the textboxes throughout a
presentation, then you must use code as described on this page:
