Which operating system do you used?
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.
Restart ADE and it should be deactivated at this point.
Should the other way not work for registry remove try this:
- Close all applications.
- 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
- Select the Adept key.
- Choose File > Export.
- In the Export Registry File dialog box, select Selected Branch under Export Range. Enter a name and location for the backup registry key, and then click Save.
- Right-click the Adept key and choose Delete.
- In the Confirm Key Delete dialog, click OK.
- Close the Registry Editor.
- Open Adobe Digital Editions and reauthorize.
Thank you so much!! This method worked, and I was able to authorize another ID.
