The kindle cloud reader has removed the cloud and download tabs. But when you open the book, a downloading progress will show at the bottom-right corner. Please just keep this book open until it has downloaded successfully. Then run Epubor kcr Converter to remove DRM and convert kindle books to drm free files.

While the automatic download with the new Kindle Cloud Reader worked yesterday as described, it does not today. Whatever I do and even with a long waiting time, the download does not start.
No message shown, just not starting the download. I'm using Macbook Catalina 10.15.6 with Chrome 84.0.4147.105 and Cloud Reader PlugIn.

ePubor ultimate worked for me since I got it.  It stopped working yesterday.  (With purchased books downloaded from Amazon page My Content and Devices. )  What is happening?  Thanks
10/27/2020 18:56:43
I installed kindle 1.24 on windows 10, but it gives an error "Registration failed. Please try again (401)"
10/29/2020 09:25:43
Thank you for asking. This is a kindle app bug. You can close this kindle for pc and try to register again. This issue should be fixed at then. Also your kindle app may be registered successfully already.
10/31/2020 00:19:45
Thank you so so much- I was finally able to convert a book that I've been needing desperately for my thesis!

so frsutrating. I spend 30min trying to figure out how to convert my ebook. and then you just output a text file syaing I have to pay for it... WTF ? is that what you call free trial ? its useless
12/14/2020 08:58:22
No matter which way you are using, this is the right steps. Yes, the trial version only converts 20% content of each book. To obtain the whole content, please use the licensed version.
If you prefer something free, please try Calibre.

Is it possible to remove drm and back up kindle books without a kindle usb device if my Mac is running 11.02 Big Sur?
02/18/2021 11:23:54
Sure, if you don't have kindle eink device, you can patch your kindle for mac for removing kindle drm>https://www.epubor.com/patch-kindle-for-mac-on-mac-catalina.html
02/11/2021 16:14:58
Very disappointed. I bought lifetime license to get something easier than Calibre. I just saw that it does not work with Big Sur as Kindle 1.23 is not allowed on this version. I'd like to get my cash back.

I've come across 2-3 books that need the latest version of Kindle to be read. If I keep Epubor running in the background then those books don't get downloaded. If I close Epubor, only then Books get downloaded, but then Epubor isn't able to remove DRM and asks me to delete the ebooks and re-download the book, while keeping epubor running in the background.

But running the Epubor in the background doesn't let me download the books... Are you getting me ?

09/22/2021 09:41:00

Thank you for contacting us. Yes, I got you. That's because your kindle books can only be downloaded via the latest kindle app. And this is decided by the Publisher and cannot be changed. We are sincerely sorry to inform you that this kind of ebooks can not be decrypted because they are encrypted with tougher kindle drm.

We are sincerely sorry for the inconvenience caused.

02/27/2022 14:57:45
It can't work if your ebook has no "via USB" option.
02/28/2022 10:05:50

To use download and transfer via usb method, you at least should have one kindle eink device registered with your account information.

If you cannot find via usb option, that's because you have no kindle eink device registered.
