When you download a book from a library or buy an eBook, open the book from the Browser download window and the book opens in Adobe Digital Editions.
If the book does not open in Adobe Digital Editions, try one of the following:
- Start Adobe Digital Editions, click File > Add to Library and browse to the book you want to open in Adobe Digital Editions.
- Drag the book onto the Adobe Digital Editions application icon. The book opens in Adobe Digital Editions.
When Adobe Digital Editions opens your book, it confirms that you have the permissions to read it. Many books are Digital Right Management (DRM) protected. If it is not a protected book, you can open it and start reading.
However, if it is a protected book, you have to authorize Adobe Digital Editions using either an Adobe ID or a Vendor ID.
You can authorize using an Adobe ID or a Vendor ID. By doing this authorization, you associate the book with your ID. If you later open the book on another computer, you can use the same ID to open the book.
In the dialog box that opens, select Adobe ID as your eBook vendor and then type in your user name and password.
If you don't have an Adobe ID, click the Create an Adobe ID link. After creating the ID on the Adobe website, close the browser window, return to Adobe Digital Editions, and type in the newly-created Adobe ID.
For more information on creating an Adobe ID, see Manage your Adobe ID account.
If you choose to authorize without an ID, Adobe Digital Editions allows you to read a book only on the current device. You will not be able to read it on other eReader devices or other computers (or the same computer if you re-install). If you don’t plan on moving your books to other computers (or re-installing), you can authorize without an ID.
Adobe recommends authorizing without an ID only if you are extremely sure you don't plan to transfer your eBooks.
For more information on authorizing without an ID, see this blog post - Adobe Digital Editions – Anonymous Activation.
