I have a Kobo Glo and I am now getting the following error message "Your eReader is not authorized to open this book. Because you previously deauthorized your eReader, you need to reimport the book using ADE". I have tried reimporting the book, and even returning the book and then reborrowing it before reimporting it to my Kobo. I have tried deauthorizing the reader and then reauthorizing it before reimporting it to my Kobo. Deauthorizing and reauthorizing my Kobo worked a couple of times, but not any longer. I have uninstalled my version of ADE and downloaded and installed the latest version. I have contacted Adobe and they checked my Adobe account and authorizations and was told that I still have unused activations and my authorizations appear to be in order. I can read my books on my MacBook using ADE, and I can even read them using ADE when I click on my Kobo icon in ADE sidebar and open the book. ADE seems to be working as advertised, but my Kobo is not cooperating. I have contacted Kobo as well and they say it's an ADE issue and will not discuss it further. I have not done a factory reset on my Kobo as I don't want to lose all my purchased eBooks. I have checked out a few threads regarding similar issues, but none with my particular error message. Any suggestions are appreciated as I feel I have tried everything, save a Kobo reset, or trashing the Kobo altogether. Thanks
Thank you!!! It worked! I was getting so sad.. I just got my ereader for Christmas and nothing was working!
I was close to tears and ready to throw my Kobo out the window but then I found this post and it worked! Thank you SO much for your helpful, step-by-step advice! This made my day!
Thank you, that really worked but not first time, grrr. Adobe "quit unexpectedly" but as it does it almost every time I use it, that's not unexpected anymore.
Thanks so much for your help.
THANK YOU! I just bought a Kobo Libra 2 especially for reading library books. The lack of access due to the "authorization" problem was making me crazy! This set of instructions worked like a charm. Thanks again!
THANK YOU!!! I have tried all of the tricks others suggested. This was so easy and it worked like a dream.
I have also struggled with this problem for months... somehow something I did in the right order worked, but I couldn't tell what. I will save this and try this next time. Thanl you. This issue almost makes me hate my kobo!
After factory resets, deleting and downloading ADE. Deauthorizing computer and ereader (Kobo Clara HD) and spending time on the phone and chat with Rakuten Kobo AND Overdrive assistance, this method actually worked. I think the trick is the NEW Book part which PROMPTEd the computer to ask for authorization. Some weird quirk. I was ready to give up. So thank you Shannon!!!

Things I tried which eventually worked (I'm not sure what the key bit was!): Deleting the book files from ADE and my kobo, and then looking for any more within file explorer - I found old files within the kobo folder as well as within the Adobe Digital Editions Folder. I deauthorised everything and then unplugged the ereader/closed ADE. Then plugged in the ereader and reauthroized the ereader, which automatically did the computer. I then downloaded an entirely new non-DRM book (one picked at random) from my library - I'm wondering if the non-protected nature was important? - and added it to ADE and then the ereader. I then re-downloaded the problem DRM books, and added those to ADE, then the ereader. It's worth noting I decided against flicking through the pages within ADE, just in case this had been causing problems (sometimes this has caused ADE to freeze for me). I then safely-removed the ereader, and voila! Even though the DRM books displayed black covers, the non-DRM was visible, and when I clicked, they opened, much to my surprise! Good luck!
Thank you for sharing - I had authorized/de-authorized my devices multiple times, deleted and downloaded books to no avail until I saw your point about a non-DRM book. I tried this and for some reason it works. Every time I want to copy a book onto my bookshelf, I copy this non-DRM book as well. Otherwise, it does not work. It is not perfect but I am so happy to have this function working. Thank you so much!
I tried everything here, and your solution is what worked for me! I piggybacked the problematic DRM book with a non-DRM book, and voilà! Thank goodness for the reader community!
Oh my goodness! I have quite literally spend over a week working on this. I bought a new Kobo (my original was over 10 years old!), spent hours on the phone to Kobo, tried asking Adobe (like many others was told my use of a free program didn't warrant them giving me any of their time) and have been scrolling community forums like this one for DAYS. Your solution to download a non-DRM book finally WORKED for me!!! I didn't really know how to find a non-DRM book in my library so used the filter options and selected a PDF book and now ALL the books I had been trying worked. I am so relieved and grateful that you spent the time to add this information to the forum. This has literally been the only thing to work for me.
Thank you for sharing. I have spent hours trying different suggestions, but this one actually works. I can now read my library book. Again, thanks!!
I have been tearing my hair (what hair?) out for literally hours on this: I did not fully read the above response (I was getting fed up), but had a look (with W10 file explorer) at the file structure on the Kobo when plugged in, and found a load of adobe-related folders with numerical names, and what looked like Adobe ID codes inside. I deleted all ot these, and maybe other ones as well (they are now gone, and I didn't think to screen shot the contents before deletion - after all, nothing else so far had worked, so why should this?). I then started ADE on the PC, authorised it, then inserted the Kobo and authorised that, then copied a 'new' book across - and it worked. I went to bed, hapily reading a book I am fairly sure I read years ago (on paper) - oh well.
I shall attempt to upload an image of the current folder structure - it doesn't seem to conatin the same stuff that I deleted, but gives an idea.
If in doubt, delete every folder on the Kobo that is ADE-related! If this ever happens again, I wil attempt to show what needs to be deleted more carefully. For now I am happy.
PS This is certainly a Kobo issue, and they should fix it. One can hardly expect Adobe to know what the Kobo stores inside itself. They (Kobo) must have discovered the cure that I found, surely?
Good luck, Martin
...and a few days ;ater, the fault was back - oh well, I tried.
Have you tried making sure the 'new' book you transfer at the same time is non-DRM?
I don't know why transfering a non-protected book would help, but as it happens I have just today tried copying some - they copy across OK and can be read - but previous and subsequent protected books cannot be read. I have tried more tricks:
* deleting the activation file in F:\.adobe-digital-editions, then re-authorising
* copying protected epub files manually from PC to F:\Digital Editions using File Explorer
* Uninstalled, cleaned registry and re-installed ADE v4.5, then re-authorise both PC and Kobo
Nothing works. I am getting fed up now! I will try your suggestion (the order differs), but am not confident...
Mine is now working - but I couldn't tell you why. I am now using ADE v3 (tried 2, 3 & 4.5 more than once) and keeping my fingers crossed. I think the issue is related to with Microsoft .Net, as several refs to that appeared in the W10 event log when the failures occurred - so perhaps a Windows update changed something? I have nearly thown my Kobo in the bin. Our library was using Cloud Library for a while, and that worked OK, then they switched to another provider, who uses ADE.

Thank you so much for these detailed instructions! They worked wonderfully for my old Nook, downloading books from our public library. I HAD been successful with downloading books from the library until about a month ago (June 2020) and suddenly Adobe Digital Editions decided that my Nook was not ok for "copying" from my computer. This work-around did the trick!
I have an original Kobo Aura, and despite all these tricks, I could only get ADE 4.5 to work intermittently. In the end I uninstalled it and installed ADE 2.0. It worked perfectly first time and I have been able to download my library books again easily. For my purposes, I can't see the difference between 2.0 and 4.5, so I am happy. - and it took much less time than faffing around authorising/ deauthorising my Kobo and computer.

I had the same issue with this on a Kobo Aura with library downloaded books
. I tried authorizing downloading a new book, reauthorizing and all of the other fixes posted on line. Nothing worked until I went into settings on my e-reader, then device information, then update check. As soon as update check ran it loaded all of the missing book information and the books were present and readable. Also, if you have an overdrive account set up you can search for books using the search function on your e-reader and download them directly to the e-reader. Never an issue with this but the selection may be different than what you can find on your library site.
Do you get the feeling Rakuten would prefer that you purchase books rather than borrow them?
I am living the same nightmare as everyone else and I cannot believe this fiasco has been going on this long. I bought a Kobo in October and spend hours in order to finally load one book onto it. Yesterday I gave it a try and hit that same darn message "Your eReader is not authorized to open this book" and so on. I spend hours trying to figure it out and then found this group. How on earth has this problem been going on since 2016? I only bought the Kobo to read library books, otherwise I would have gone with the Kindle. I have worked my way through the instructions to delete this, load that, remove authorization, add authorization and so on. It simply doesn't work. I now have to either return it to Amazon by the end of January, throw it in the garbage or perhaps try downloading 3.0. How utterly ridiculous.
Sorry Mary, This is just part of the joy of owning a Kobo! I have downloaded Adobe 3.0 in the past and that did work. Following my instructions above - especially downloading a fresh book - usually works. Unfortunately, ereaders are not a big marketing item anymore so there's not many brands to choose from. I guess lots of people use their tablets. Looking on the internet, it would seem that some Kobos have OverDrive library built in. Not mine, unfortunately (Glo). Have a look.
I have had my Kobo for a very long time and sometimes I can go for a whole year without hitting the problem. When this one dies, I'll probably buy one that downloads from libraries over wifi. I'm not going down the Kindle path. I accept Kobo doesn't care about me much although I do buy the odd book off them.

I found another way to fix this. I was trying to transfer my 14 days Book A loan from the Open Library to my Kobo Wireless eReader Version 1.9.12 but it was giving me the error. I tried everything mentioned in this thread (de-authorising, resetting my eReader, downloading a new book, deleting the old one), nothing worked.
I then downloaded another book (Book B, 21 daysloan) from a different library (I used London Libraries Consortium). I transferred that loan to my eReader and it worked.
I re-plugged my reader and transferred Book C loan from the original library (the Open Library). I picked a public domain book (with expired copyrights) that was available to download and keep forever (not a loan).
I transferred Book C using ADE to my Kobo, unplugged it and it was working fine.
Finally, I re-plugged my reader and transferred Book A (a loan) to my eReader. I unplugged it and it worked as well 🙂
I suspect one of the below fixed the problem:
1. Using the same library, downloading a book that's not a loan and that you can keep indefinitely
2. Borrowing a book from another library
Let me know if this helps
I have a Kobo Libra H2O on which I can read every book, but library books. De-authorize and authorize etc doesn;t help at all.
Too bad! Any good tips welcome! Thank you.

I also grappled with all the problems you are having and, after much research, I decided to buy a Kobo Libra which has an app for Overdrive which connects directly to your library without having to fight with Adobe Editions. Now I am reading again with no issues and Adobe Editions is history.
