Yeah, if you don't have K4PC you won't be able to load it to kindle so that leaves a couple of things unless you have an older kindle. I can't remember which one, but NOT a tablet one. Kindle or Paperwhite work, not sure about Oasis.
1. Download the K4PC app to your PC, register & download your book. New ones won't work, you need an older version. I have it saved. If need it I can load it online so you can download it. It's 1.17.44170 or you can get it from You are not allowed to view links.
2. Give someone with K4PC already installed your Amazon login (I really don't recommend that unless you've known the person a while.
3. See if you can "loan" the book (If you bought it, I don't think you can with Kindle Unlimited), to someone. I've actually used this a lot.
4. If it is a Kindle Unlimited loan send me the link to the book (not to your content) & I'll download it for you on my pc. Let me know if you need my email.
When I do what you have said, I only get the option to save it to one of my Kindles and it's not in my downloads, it only goes to the requested Kindle. Do I have to add Kindle fore my PC to the list of Kindles allowed to receive books?
Are they trying to stop us sharing do you think?
Thanks for trying to help and please advise if I can do more.
