1. Please download the latest ADE 188.8.131.52137
2 The first time you open a protected book, ADE will ask you to authorize your computer [Help -> Authorize Computer] . The best way to do this is to supply an Adobe ID or Vendor ID, associating the book with your ID. If you later open the book on another computer, you can simply supply the same ID to open the book.
If you don’t have an Adobe ID, click the Create an Adobe ID link. After creating the ID on the Adobe website, you can close that browser window, return to ADE, and enter the newly-created Adobe ID.
3. Drag and Drop ACSM FILE to ADE.
