E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 [2012]

Hello,

 

I downloaded an e-book from lulu.com yesterday.  It was an .acsm file, which forced me to install Adobe Digital Editions 2.0 in order to view.  I installed it without authorizing and browsed the book for a few minutes then turned off the program.  Later I returned to read it but there was a message about some licence key being broken or something, with E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 in the error message.  I tried to authorize ADE to see if it would help, but it gave me a message saying "Digital Editions encountered an error on the activation server", with the familiar E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 code.

 

I tried removing the book from the library and reimporting it, but now it won't even do that without the same error message.  I've tried deleting the .acsm file and redownloading it, unistalling ADE and reinstalling it, made sure the firewall allows acces to the internet, and keep getting the same message.  I'm running on Vista.  It works with DRM-free .pdf's I have, but I can't download any of the sample books on Adobe's website to test further because the server doesn't respond.

 

Any ideas?

Anyone else coming here with this issue, and Unable to Erase authorization error, here is how I solved it on Windows 10.

 

Windows key (start menu) > search Add or remove programs > uninstall Adobe Digital Editions

 

Run: Windows key + R > regedit > HKEY_CURRENT_USER/SOFTWARE/Adobe. I had two extra "keys" (folders) sticking around after the uninstall, Adobe Digital Editions, and Adept. Right click both and delete.

 

Reinstall ADE from Adobe website. Help > Authorise Computer again.

Using a Mac with High Sierra. Using ADE 4.5.8.182914. When I try to load an ebook, I get the error message "E_AUTH_BAD_DEVICE_KEY_OR_PKCS12", which is a deauthorization error message. I have researched and know that I have to go to Users/[[Your user account]]/Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash. The problem is that there is no Digital Editions within the Library/Application Support/Adobe/folder. I've also done a search on my computer for an activation.dat file, but there is none. I've tried uninstalling and reinstalling ADE. I've tried uninstalling and installing an older version (3.0) with the same results. Any suggestions?

erreur E_AUTH_BAD_DEVICE_KEY_OR_PKCS12

J'ai un mac et malgré toutes les solutions essayées grâce aux différents forums, rien n'a fonctionné. Finalement la seule solution qui a marché tout de suite, c'est d'ouvrir une nouvelle session (invitée), réinstaller ADE avec les mêmes codes, j'ai d'ailleurs retrouvé ainsi toute ma bibliothèque et j'ai pu télécharger tous mes nouveaux livres (empruntés à une bibliothèque gratuite).

J'espère que cela marchera pour tout le monde

Hello, I found this error " E_AUTH_BAD_DEVICE_KEY_OR_PKCS12"   in my desktop computer (Win 7). This error happened after two or three months I did not open the digital editions.

I tried, uninstalling and installing the ADE, reloading the .ACSM file. The one that worked was "deauthorize computer" as showed above “Ctrl + Shift key and the d key” and then authorized it again and loading the .ACSM

I think ADE is far from being a good tool.

From: students.universityreaders.com

If you have received the error message "E_AUTH_BAD_DEVICE_KEY" or "E_AUTH_BAD_DEVICE_KEY_OR_PKCS12" - what do you do?

Solution: Deauthorize and reauthorize Adobe Digital Editions.

For Adobe Digital Editions (Windows PC and Mac)

  • De-authorize Adobe Digital Editions (from library view, CTRL+SHIFT+D or CMD+SHIFT+D).
  • If you have previously downloaded your book to another computer, please use the same Adobe ID when authorizing subsequent devices.

For Bluefire Reader (iOS and Android mobile devices)

  • Click "Info" at bottom right of Bluefire Reader.
  • Click "Deauthorize" and confirm.
  • Click "Authorize" and enter your Adobe ID credentials.
  • After following the above steps, please try downloading and opening your book again.
  • Verify that your computer has access to the internet. If it does, check any proxy, firewall, or antivirus settings that may be preventing Adobe Digital Editions from accessing the internet.

Hey,

Thank you so much for the posting. However, I attempted to erase the authorization, but it told me that it's unable to erase the authorization at the time, even though I entered the correct password. I have tried multiple times. But it's still not working. I don't why. Is there any other procedure that I have to follow in order to be able to de-authorize the Adobe Digital Editions?

If due to some reason, you are unable to deauthorize ADE, follow the below steps:

Mac: Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.

ADE will be deauthorized now.

Now Authorize ADE again.

Windows:

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

Right-click the Adept key and choose Delete.

In the Confirm Key Delete dialog, click OK.

Your authorization will be deleted.

ADE will be deauthorized now.

Now Authorize ADE again.

I have now corrected this error!!

at last....

I was advised that if you open Adobe Digital Editions and then press “Ctrl + Shift key and the d key” at the same time a pop up box will appear “ Erase computer authorisation” if you click the button on the right “ Erase Authorisation”.

Then the first time you use Adobe Digital Editions, you will be asked to authorise the software with your ID. Should you not receive this prompt, click ‘Help’ and ‘Authorise this Computer’

And it worked!!!

I noticed that you are running on Windows Vista which ADE 2.0 does NOT officially support. Have you tried any other Windows platform like Windows XP or Windows 7?

Unfortunately Vista's all I got.  That could very well be the problem.

I finally was able to download a .acsm file from Adobe's sample books page.  It evokes the same error message.  No progress.

Also, I attempted to see if I could view the file on my phone instead of my computer, but seeing as how the first (and only) time I opened the book ADE was not registered, and therefore rights were limited to that one device, it won't let me view it because of that whole DRM thing.
