Hi, I would really like to get step 3 to work. I have installed Kindle version 1.26 as you stated and used "chmod". I have downloaded books the way you stated.
I have checked that there is no "kcr" files in my Kindle library. Still Epubor Ultimate writes "Kindle DRM" with big red letters on many books I wanted to convert.
Then login your kindle cloud reader on chrome browser. This time you can download your kindle books.
If you need more support, please contact me via epubor.iris@outlook.com to get further assistance.
Textbook are not supported.
thanks a lot
Please install the kindle cloud extension to your chrome and then try to download and pin the book.

But your kindle cloud reader book still can be downloaded. Just click the book cover to open this book and start the downloading. You can see a downloading process at the bottom right corner on your open book.
If your book has been downloaded completely, right click the book and there will be menu include "open book"Remove book".
Then you can use Epubor kcr converter to remove DRM from them.
Any more problem, please feel free to contact us.
Yes I see what you are saying. That works for the other books in my cloud library, but for the specific book I am trying to download it says on the Kindle Cloud Reader, "We're sorry. Kindle Cloud Reader can't open this book, but you can read it with our free kindle app. To receive a download link enter your email or phone number". The download link is for the kindle app (it takes you to the app store). This message pops up the second I click on the book on the cloud reader.
As stated in my first comment, the book on the amazon website posting also says "title is not supported on kindle e-readers", which means it will not open at all on the cloud reader. The moment I click on it I get the error message I copied and pasted above.
The name of the book is rethinking disability by Jan Valle and David J Connor (2013) 3rd. edition. Pink cover https://tinyurl.com/y76vxwh3
Thank you
Hello,
I am facing the same issue regarding converting some books which is showing the same error:
"We're sorry. Kindle Cloud Reader can't open this book".
Is there a work around solution for this problem? I have purchased few books from Amazon and desperately need them in pdf formats to study.
Kindly advice and help.
Br, Amit
I forgot to mention. I am using Catalina 10.15.6 and Kindle version 1.29 (58033)
I also tried all options and help I could find for ePUBOR Ultimate, but I am still seeing the error "Kindle KFX".
But here is a workaround, please use Kcr converter to convert kindle books downloaded via kindle cloud reader to drm free azw3, epub, pdf and mobi format according the instructions in this article.
Kindle cloud reader is showing "Kindle will no longer support downloading books for offline access in the web browser. You can continue to read your existing downloaded books until you sign off from your account." when I had my computer offline. When it is online Kindle Cloud Reader no longer has a Cloud/Downloaded tabs, neither on Chrome, or on the Edge browser I just tried.
Very disappointing. Unless there is a another way to get kindle books into Epubor's KCR Converter it appears my purchase is no longer doing what it promised to do.
But your kindle cloud reader book still can be downloaded. Just click the book cover to open this book and start the downloading. You can see a downloading process at the bottom right corner on your open book.
If your book has been downloaded completely, right click the book and there will be menu include "open book"and "Remove book".
Then you can use Epubor kcr converter to remove DRM from them.
Any more problem, please feel free to contact us.
Let's accept it : Amazon's upped their game, that's what's happened. I spend a whole day of hit & trials, multiple times of installations & uninstallations but it just doesn't seem to work. Basically your software works through Kindle Cloud Reader but amazon seems to have condemned KCR as its not downloading any books anymore and gives a message : We're Sorry, KCR can't open this book, but you can read it with our free kindle app. Please enter your email or mobile number to receive the download link.
Now if you have a valid solution for this then please share. Otherwise you better take this blog off because it doesn't work.

First of all, thank you for using our kcr converter. I guess I know what happens to this book.
1. Please note some books (etextbooks) are only downloaded via Kindle for pc/mac. This is decided by publisher and the download information clearly lists on the product detailed page. So If this book doesn't support by Kindle cloud reader, you can not download them via Kindle cloud reader. You can now go back to your ebook product to check this point.
2. Kindle cloud reader books are now downloaded automatically that's why Amazon removes the download and pin tab. They think this will improve the user experience.
But your kindle cloud reader still can be downloaded.
3. If your kindle cloud reader ebooks can be downloaded, then KCR Converter will help you convert them.
Any more problem, please feel free to contact us.
Have a nice day.
After opening a book in the Kindle Cloud Reader, it takes a while till the download starts automatically. Approx. 10 secs in my case. So, patience is helpful.
Starting the KCR Converter after the downlad has completed, shows all downloaded books and allows DRM removal and conversion.
Well done. Thanks
What to do ?
I tried every think and every update...

Hi. I'm using macOS Big Sur Version 11.0.1 (20B29).
I purchased a LIFETIME SUBSCRIPTION to Epubor Ultimate yesterday. I'am a senior Software Engineer and after trying all of your tutorial on how to remove the DRM from my kindle files, exhaustively, I'am no further forward. I bought the software to remove the DRM from my Kindle books that I have stored on my Mac. Not a device a computer. The Python tutorial, being very familiar with it, sounded promising, but to no avail.
Your software will NOT remove the DRM from Kindle books. I'll apply for a Refund.
Thank You
Steve MacEwan
Any more problem, please feel free to contact us.
Hello there,
I have put off upgrading my MacOS so that I can continue to remove the DRM from my Kindle books. You said that there is a work around if you had pervious converted books before the upgrade to Cat. Does that same work around work for Big Sur and what is it?
Any more problem, please feel free to contact us via support@epubor.com

Hello,
I have Kindle v1.32.0 on Mac Big Sur 11.5.2. In terminal, I got "No such file or directory" when trying to run the command "sudo chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test"
Followed your advise to Gary, I downgraded Kindle to version 1.31(deleted the higher version completely, then installed the older version). Tried the command in terminal, still got the same response.
Then I searched the machine, but didn't see any folder named "MacOS". There's a folder "My Kindle Contents", but no file resembles "renderer-test".
What should I do next?
Thank you for using our software and sincerely sorry for this issue. Please delete this kindle 1.32 and then install 1,.31 and then redownload kindle books to remove drm.
If you are still failed, please feel free to contact support@epubor.com to get further assistance.
