Logging in with Kindle for PC 1.17 stopped working as of today (2020-11-01)

The 1.17 version of Kindle for PC has stopped working, because it can no longer log into Amazon (amazon.de).

It complains about wrong E-Mail or phone number when entered the correct on. Hopefully this is a temporary issue.

Here is what I tried so far:

• Logging in with Kindle 1.17.0 (44170) does not work
• Logging in with Kindle 1.17.1 (44183) does not work
• Logging in with Kindle 1.25 works

When logging in via Kindle 1.25 I get asked to enter a captcha and click on a link I get via email. So I guess the login process has changed with newer versions of Kindle? I also disable 2FA for my account, but that also did not help.

It seems an existing registered kindle for pc 1.17.0 still works, only new registration fails.

@SvenErik1968: Interesting. I use 1.17.0 (44170). Do you have a link for your version?

[PyroDevil]

@SvenErik1968: Nevermind I found a 1.17.1 download, however logging in still doesn't work. I login to amazon.de. Maybe that is a reason?

[PyroDevil]

Just to clarify logging in with 1.25 worked

If this is a change from Amazon, maybe they are rolling it out regionwise or over time. I log into amazon.com from Norway.

@PyroDevil, I am running v1 1.17.1 (44183) on Windows 10, and I just tested it, and I could log in and download purchased books...

Someone over at MobileRead reported this. They were able to resolve it though. They installed and registered the latest version of Kindle for PC. Then installed version 1.17 and were able to register it with the extra step of approving the sign-in attempt on their phone. (Always making sure the automatic update box was unchecked.)

Just wanted to pop in and say the fix that @ElleKayEm mentioned does not work for me. I was able to log into the newest version of Kindle for PC, then I installed 1.17.1 over the top and it still tells me to enter a valid email address.

Ok, I think I have it sorted. Had to install a 1.24 version (https://www.epubor.com/how-to-downgrade-kindle-for-pcmac.html), then register/login/whatever, then install 1.17 over the top. That gets past that hurdle at least, haven't tried running a book through yet.

@sean-perryman: That worked for me as well. Thanks! I think it was cause by a forced update for me. So I also followed a post on mobile read to disable the force update permanently.

I also couldn't login any more.
@sean-perryman your method worked for me as well, thanks!

I had this issue too tanks @sean-perryman your fix worked for me.

Mine just stopped working completely the Week of 02/14/2021. Just stopped opening. I tried uninstalling, then uninstalling with Revo Uninstaller, turning off AV for a moment, and installing while unplugged from the internet to see if it would launch at least.
I've tried all of my saved install files that used to work, 1.17 44170, 1.24 51068, and 1.26 55076 All will install but none will launch at all. They icon just blinks once and don't even show up in task manager.

[ElleKayEm]

What about installing the current version?

[bhillyer]

An update. I went to other computers I had Kindle for PC 1.17 installed and even though updates were turned off on both, one automatically updated anyway. I verified it updated, and that the option to Auto Update was still unchecked. The other computer I turned off wifi before launching, then connected and downloaded, and even though all books were downloaded with KfPC 1.17 only one was able to convert in Calibre 4.23 with DeDRM 6.63 and 6.8.0 . I got the protected by DRM pop-up on 5 books purchased.
Something is definitely up.
