Resolution: Follow these steps:

1. Uninstall Adobe Digital Editions using one of these two  methods:
   • Start > Programs > Adobe > Adobe Digital Editions  > Uninstall
   • Start > Settings > Control Panel > Add Remove  Programs
2. Initiate Uninstall
3. In order to remove all remnants of Adobe Digital Editions /  Adobe Adept from the machine a "Registry Edit" will need to be  performed:
   • Start > Run > Regedit
4. Search for HKEY_CURRENT_USER > Software > Adobe >  Adept and Delete the full "Adept" folder
5. Remove only the structures that are under the "SOFTWARE"  extensions. This will remove the Adobe ID / License and Activation Keys

   • C:\data\my digital editions
   • C:\my documents\my digital editions
7. Delete any documents within these folders:
