@jyg someone reported a similar issue with the deken installation on a Windows OS on github. I can not reproduce this on Linux and i don't know what could be causing it, so my suspicion was that it is somehow related to Windows security permissions. Are you using Windows? Does this happen with other libraries as well? Unfortunately, there is not much i can do about it, but i'll test as soon as i have access to a Windows machine.
For now, if you want to stay up to date you can download from github and set the path manually in pd settings.

Edit: just saw that you created another issue about this on github. I'll close it because it is not related to the development of this library, but we can continue the conversation here.

Sorry, I mistook the OSes. On Windows it's OK, although I get some error messages (see video below).
At end, the files and folder structure are copied.
BUT on MacOs BigSur The folder structure is not copied, neither the contained files (Examples and audio)

@jyg i just uploaded a new version 0.71.1 to the deken repo. Can you test if this works for you?
