    Help with opening epub files in Digital Editions

    danno4 Level 1

      Hello,

       

      I'm having some issues regarding opening epub files in the digital editions program.

      The file is an epub file, which is recommended to use this program to open. I need this for school work.

      I'm getting the 'Error! Check Activation' message everytime I attempt to open this file.

      I've attempted to deactive, reactive, but the program gives me an error, and tells me to retry again later.

      I've also attempted to reinstall multiple times, and still no success.

      I've attempted to delete the key file from the registry, and also had problems where it wouldn't let me delete it.

      I would attempt to install an older version, but for my class I need this current version of Digital Editions.

       

      Any help is much appreciated,

       

      Thank you for your time.

          If due to some reason, you are unable to deauthorize ADE, follow the below steps:

           

          Mac:

           

          1. Go-> Go to folder.

          Go to folder dialog will appear.

           

          2. Type   ~/Library/Application Support/Adobe/Digital Editions

          drag the activation.dat file to the trash.

           

           

          ADE will be deauthorized now.

          Now Authorize ADE again [Help -> Authorize Computer].

           

           

          Windows:

           

          Choose Start > Run.

          In the Open text box, type regedit and then press Enter. The Registry Editor opens.

          In the left pane of the Registry Editor, locate the following registry key:

          HKEY_CURRENT_USER\Software\Adobe\Adept

          Right-click the Adept key and choose Delete.

          In the Confirm Key Delete dialog, click OK.

           

           

          Your authorization will be deleted.

          ADE will be deauthorized now.

          Now Authorize ADE again.
