When I click on a downloaded library book it appears in my PC Reader app. but not Adobe Digital Editions. How can I get it to go to ADE directly?
You need to set the default application to open as ADE. When you download an ACSM file, select the option to save it to disk instead of opening directly. The you can right click on the file and choose 'Open With.' Select 'Choose another app' and select ADE. There is a checkbox that says something along the lines of 'Always use this app to open XXXXXX files.' Once you do that it will always open in ADE.
