    Check Actiation


      I am getting the error message " check activation" I have tried versions 4.0, 3.0,and 2.0.1. Changing editions hasn't helped.

      Any ideas?

          Hi Michael,


          Your authorization file is damaged and it needs to be cleared out.


          You need to delete out a few registry keys to clear the activation for ADE. 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:


          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.
