My computer has made Adobe Reader my default for downloading library books and I need to change it to Adobe Digital Editions on my PC that runs Windows 7. How can I do that?

I can no longer download books from my library because the default program is Adobe Reader and my library uses Adobe Digital Editions.  How can I make my computer use Adobe Digital Editions as the default?
