    Activation Error

    MagisterAlbus

      I have downloaded an e-book from Harper-Collins but, when I try to read it, I get this message: Error! Check Activation.

       

      What does that mean?@

          Hi Magister,

           

          You need to manually delete the activation file and then resign in. Please follow these steps:

           

          You must have administration authority.


          On Windows it can be found here:
          Open Windows Registry by using the command prompt and typing 'regedit' or by opening the start menu and searching for 'regedit'.

           

          Search for the following folder:
          HKEY_CURRENT_USER\Software\Adobe\Adept\Activation

           

          The 'Activation' folder can be entirely deleted.

           

          On Mac it can be found here:
          In Finder, find the 'Go' option on the menu bar and click 'Go to folder' and type the following in:


          ~/Library/Application Support/Adobe/Digital Editions/

           

          Delete the activation.dat file within the 'Digital Editions' folder.

           

          Restart ADE and it should be deactivated at this point. You should be good to sign back in.
