    e_auth_bad_device_key _or_pkcs12 for windows 7



      Looknig for help please with ADE.

      Using PC with Windows 7 and Kobo reader.\Can no longer download e-books from library.

      Get error: E_AUTH_BAD_DEVICE_KEY_OR_PKCS12.

      I have seen others with this issue but I do not understand the fix given, it seems to be for a MAC.

      Please help to let me know how to fix this issue on a PC running windows 7.

          Two possible solutions (both apply to Mac and Windows).

          Unfortunately, ADE is so random in its errors and error messages I can't promise either will work for you,

          but others have found one or the other works for that error message.  Good luck


          Two possible solutions ...

          1) ~~~~~

          Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

          Uninstalling and reinstalling does not help.

          Unfortunately, it often then gives misleading error messages about what is wrong.

          A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.

          This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).

          Restart ADE, and then reauthorize with your (old) Adobe ID.

          In extreme cases on the mac, the following extra step has helped some people.  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 Access hidden user library files | Mac OS 10.7 Lion. http://forums.adobe.com/thread/1265248?tstart=0

          2) ~~~~~~~~~

          There are lots of bugs in ADE2.0 (and 2.0.1).  Try replacing ADE2.0 with the older but more reliable v1.7.2.

          (You can have them both installed at once if you like.)

          Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.


          The forum software is sometimes corrupting the link above.  There shouldn't be a blank in 'editio ns.html'.  The following redirects to the same page: http://tinyurl.com/diged172

          Some people have found ADE trying to upgrade automatically. 

          It appears (not 100% sure) that if you install ADE2.0 as a new install (not as an upgrade) that your 1.7.2 will continue to run.

          Probably best to say no if 2.0.x installation asks if you want to migrate your library.
