"No permission to copy book" is the error I receive when I drag and drop ebook icon in Adobe Reader 3.0 on my computer (Windows 10) to the Nook icon, also in shown in Adobe 3.0 window.
Nook support told me to use Reader 3.0 rather than the latest version, 4.5 etc.
My Nook is ancient. It hasn't been used in years. However, it tells me that it is eager to return to active duty.
[Question moved to the Digital Editions forum. -Mod.]
Adobe Reader and Adobe Digital Editions are different products.
