I am trying to load my KOBO ereader with EPUB books from Overdrive and I receive an activation error. I checked with overdrive and they told me to reset my Adobe ID because I have too many activations (on devices and computers). How can we solve this so that I can download my library books to my KOBO?
Close all applications.
Press WINDOWS + R.
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
Remove the Adept Folder.
In the Confirm Key Delete dialog, click OK.
Close the Registry Editor.
Open Adobe Digital Editions and reauthorize..
quit Adobe Digital Editions.
Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
If you are using 10.7, see https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html
Open Adobe Digital Editions and reauthorize.
UK (and perhaps other countries?) instructions to make your kobo work with Overdrive library books
I have a Kindle where I borrow books from my US library, but in the UK it does not work. Not wanting to jailbreak it, I bought a Kobo and hit the wall with repeated error messages preventing download.
If you get error messages such as
This title has been downloaded using a different account. Authorize this app with the same OverDrive account (or Adobe ID) you originally used to download the title.
I hope this can help you.
Today I gave a good go at piecing together the information that is around from several sources (thank you all that worked so hard to get the various bits – I needed several of your suggestions)
I hope this helps in resolving this issue:
Note: IT MUST BE 3.0
If you are unable to find the activation.dat file in Mac OS X 10.7 or later versions, see Can't see user library files in Mac OS X 10.7 and later.
The following task requires you to modify the Windows registry. The registry contains system-related information critical to your computer and applications. Before you modify the registry, create a backup copy. Adobe does not provide support for problems that arise from improper modification of the registry.
For more information about the Windows registry or the Registry Editor, see the Microsoft Support site.
If the deauthorizing process is unsuccessful on Windows, it is possible to modify the registry to remove the activation information.
Now that you have got rid of those pesky files
Go in Overdrive to your library
Borrow a book and open overdrive in a browser (I did- I do not know if it makes a difference but just in case)
When you click on the downloaded link (the .acsm file) it will ask you to authorise the device
Make sure you authorise with your overdrive credentials. I also noticed that in the drop down menu there are TWO overdrive links (actually several are duplicated). Why? Who knows?? I used the first one if it makes any difference.
Connect the KOBO reader
Now you can transfer and read your borrowed library books
It worked for me but it defies belief that this issue is around since 2014 and not sorted yet?!??
Happy reading and thanks again to all that provided parts of this text
