Q: I tried to open and read a book in Kindle Cloud Reader, but it won't allow me to do that by saying "We're sorry. Kindle Cloud Reader can't open this book, but you can read it with our free Kindle app."
A: Some books (like eTextbooks, picture books and long-text novels) can't be opened by Kindle Cloud Reader because Amazon Kindle has made some limitations on such books which must be opened with the Kindle app.
You can check whether your book can be opened by Kindle Cloud Reader or not in this way: On the product page of the Kindle book, find the "Deliver to" option under the "Buy now" button. If Kindle Cloud Reader is listed on the options from the dropdown menu, it means that you can open and download it on the Kindle Cloud Reader.
If there is no option for delivering to Kindle Cloud Reader, it means this Kindle book cannot be downloaded from Kindle Cloud Reader, which is a limitation made by Amazon Kindle. Therefore, Epubor KCR Converter does not support such kind of books, for Epubor KCR Converter only convert Kindle books that can be downloaded via Kindle Cloud Reader.
For such books, you can still try to use Epubor Ultimate to convert Kindle books downloaded via Kindle for PC/Mac desktop app.
