I have the same issue, after "Forced" upgrade of Adobe, I am unable to read my ebooks. I get message "document is licensed for different user account". I opened a support case with Adobe and this is what I got back.

We regret to inform you that our support for Adobe Digital Edition
version is only for download and installation issue. If the problem is
already pass the point of downloading and installation, I'm afraid we
can only refer you to visit the Adobe Digital Edition Support Website to
find information about this free program. You may reach this webpage

Another avenue where we can lead you to, to find additional information
about Digital Edition is through the Adobe User-to-User Forums.
(http://www.adobe.com/support/forums/).

Once again, we apologize for the inconvenience.

S oessentially, I am forced to upgrade, but they will not fix their faulty software.

Hope someone can help me.

nope, no lock so far, have a case opened with Adobe, but nothing from them so far.

Thanks.

I'm having this same problem too. And it looks like Adobe is not even bothered to resolve this problem.

Add another one to the list !!!!!

Hey Adobe -

  Next time I need to purchase books for school, can I just send you a check instead. Or maybe I will just flush the money down the toilet. That will save the time of installing useless software.  Who has time to chase down Adobe Support for this Digital Editions scam??

Thanks for nothing.

1)  If you created an Adobe ID after the installation was completed (and after downloading books)  the documents that existed before are tied to the"Unauthorized" computer activation - or if you changed your Adobe ID mid-way through   - thus when you active the Adobe ID the following error will occur:  

Error - Document is licensed for a Different User Account  (Un-license your machine by removing the Adobe ID via:          ctrl+shift+D)

     ** This fix was provided by another user who also was on this forum previously (Thank you)

Also be aware that Adobe Digital Editions does clearly tell the user "when they Activate" the Adobe ID - Confirmation request appears and "Warns" that if any documents are associated to the Ditital Editions Library on the Computer - they will no longer be readable.  - It prompts for "replacement" - once you do this - your documents are no longer usable. 

2) For the User who has uninstalled and re-installed and continues to receive errors - there is a reason behind it - the software does not cleanly remove all pieces from the machine - thus just "uninstalling" the software is not enough - the following procedure was written for Windows machines. 

If your trying to matain previous downloads of EPUB / EBOOKS - complete a back-up of your files

     -  Back up your documents that are located in the c:\data\My Digital Editions or c:\my documents\My Digital Editions (in some cases you may have to search for the My Digital Editions directory  -

1)  Uninstall Adobe Digital Editions using one of these two methods:
               Start > Programs > Adobe > Adobe Digital Editions >Uninstall

OR
               Start > Settings > Control Panel > Add Remove Programs

2)  Initiate Uninstall
       In order to remove all remenants of Adobe Digital Editions / Adobe Adept from the machine a "Registry Edit" will need to be
performed:
               Start > Run > Regedit
                       Search for HKEY_CURRENT_USER > Software > Adobe> Adept and Delete the full "Adept" folder
                               Remove only the structures that are under the "SOFTWARE" extensions. This will remove the Adobe ID / License
and Activation Keys

3)  Clear any outstanding tasks that may be associated to Adobe Digital Editions downloads
                       C:\data\my digital editions
                       C:\my documents\my digital editions
                                       Delete any documents within these folders:
                                               Restore > Tasks
                                                      Restore > Failed

4)  Delete all items in the Recycle Bin on the computer - and Reboot the machine

5) Re-install Adobe Digital Editions by obtaining the Download Adobe Digital Editions 1.7.1 Installer
for Windows from documents - kb403051 (which is the digitaleditions1x7x1.exe installer)  -   After locating the fix document - download the *exe file to your local computer

6)  Install from the location machine - running the *exe - Take all the defaults (do not change any of the installation settings).  Once digital editions installation is completed - Open Digital editions and the Setup Assistant will pop-up  -  This time utilize the "Do Not Authorize" option on the Setup Assistant

7)  After the installation has completed on the machine - take the EBooks / PDF's and place them back into the My Digital Editions directory

Open Digital Editions and click on the "Library" > Add Item to Library -  This will default to the My Digital Editions directory -  Select a book to add to the library -  Validate that the file will open.

There are a couple of things that you have to remember here

1)  Adobe's software is just that - software.  We've all dealt with Good and Bad software

2)  The company your downloading your documents from should be able to supply some level of support - espically since they are selling you the documents

3)  Adobe's support may not be great or even still "there" - but there are plenty of things that users should do when they work with the software to install it

     a)  Read the information provided on the screen

     b)  Note that after you installed Adobe Digital Editions - and you decide to "Register" with an Adobe ID / Password - post document download - that a warning screen is provided to the user - asking you if you really want to continue.

     c)  Make sure that you have information or at least additional assistance provided by the Company your downloading your Documents from - Adobe isn't forcing these companies to DRM wrap their documents - but Adobe does supply the "Reader" required to read them.  So the company selling the documents should be able to assist you in getting your documents downloaded.

4)  Just because one thing works for one or two users - it doesn't mean that it will work in all circumstances for everyone else.

In your case you "Changed" computers - dependant on the "DRM stamp" associated to the Document you downloaded - it could be set to only be opened on the specific computer that you downloaded the "original" document to -  This is not Adobe's problem -  This is a "Digital" encrypted / signed document that was "tied" to the computer you had it on -  Meaning that you should probably address this issue with the Company you brought the document from and let them know the circumstances and see if they can assist you on obtaining your documents.

If the Company that sold the document to you "locked" it and it was working just fine before on the other Computer - technically Adobe can't be blamed for the Rights the company tied to the document.

Sorry, as much as the Software can be a pain, you have to take the time to "Inform" yourself.

Several years later, here are the case n

umbers - same situation: 01

all the same problem, and all "resolved" by some

non-speaking English speaker who can't und

erstand a simple problem. I try to download a book from

a local library and get the above message. Erase, delete and

reinstall with the same result. I would be willing to pay, who

asked for free, but I would like something that allows me to

read, free, books forom my local library.

Thank you for your response.

I finally found download remnants ? or whatever from my attempts to download books from my local library. These, hidden as they were, interferred with

my attempts to download my purchases from BN and from other purchase sites. Appeals to Adobe were akin to my requests for Divine Guidance. I agree that technology should be available forproblems like this, even if one had to pay a reasonable one-time fee.

In last gasp attempt, with Nook and downloads from BN plus local library., I

deleted every remnant of any of these books from computer files. Then

reinstalled. So far no problems but I am shy about each download.

Are there instructions to solve this problem on a mac computer?

just tell me what to do, if possible

other books come through with no proble

except "mormonchslds_9781605011837_b.epub

I have opened a webcase and no one responds.  I'm having all types of issues with ADE.  First the downloaded books would show up on Digital Editions and my nook as long as it was hooked up to the computer.  Once I eject, the books disappear.  I followed the instructions for re-registering that I found on this forum.  I did this over and over again to no avail.  I guess I did it too many times because then I received an activation error.  So I called Adobe and they couldn't help.  Now I'm getting a "document is licensed for a different user account" error message.  Can you pleeeeaaaase help me?  My case number is 0182023328.
