Q. Why can’t I open the book I downloaded to my iOS (iPhone or iPad) or Android device?


First, make sure that you completed the installation of the Bluefire reader on your iOS or Android device. Bluefire is required for offline reading.

Also, make sure you have authorized it with an Adobe ID, which is required to open thes book in Bluefire. It’s easy to create an Adobe ID. If you have not done so you can follow the steps below:

The first time you open a book (which has an .acsm extension) with ADE, you will be asked to "Authorize Your Computer". The ebook vendor showing by default is "Adobe ID"; do not modify this default.

Note that you only need to enter an Adobe ID and password if you want to transfer the book to another device. If you want to authorize your computer without an Adobe ID, check the box at the bottom left corner of the screen: "I want to Authorize my computer without an ID".
