I’ve tried everything, but can’t get the DRM remover to work.

[NicolePDX]

Hi, I’m running Windows 10 Home on a fairly new 64-bit Inspiron 11 3000 series laptop. My windows user name contains no special characters (only letters) but my Microsoft password contains letters, numbers, and two asterisks. I only mention this because there was some mention of ascii characters being a problem and I’m not sure if my password could be causing an issue.

After updating Calebre to the latest version, I very carefully went through the steps outlined in the instructions:

-Deregister Kindle for PC from your Amazon account. -Uninstall Kindle for PC -Delete the Kindle for PC preferences -PC: Delete the directory [home folder]\AppData\Local\Amazon and [home folder]\My Documents\My Kindle Content -Reinstall Kindle for PC version 1.17 -Re-register Kindle for PC with your Amazon account

Here I downloaded and successfully installed the latest 6.5.5 DRM plugin for Calebre

I shut down and restarted Calibre.

At this point, my caliber library was empty, and I’d deleted all precious Kindle downloads from my download folder.

From the Manage Your Content page in Amazon, I used the “Download and Transfer via USB” on a book I’d purchased, but had never attempted to download before. I chose a Fire as my device.

I opened my download folder and dragged the fresh kindle book from there to Calibre.

When I tried to convert it from AZW3 to a MOBI, I got the “Cannot convert...this book is locked by DRM” message. See Log File below.

I’ve used and loved Calibre with your DRM removal plugin for years. It stopped working about a year ago. I’d be thrilled if you could help me get it up and running again. Please advise.

Thanks very much! Nicole

To remove DRM from a book downloaded from the website, you need to choose an E-ink Kindle, not a Fire, and enter its serial number into the plugin customization. Otherwise, download the book with Kindle for PC (make sure that you uncheck auto-update so it stays on version 1.17) and import that copy.

Ah, thank you. That worked! I swear I used to be able to do the USB download choosing a Fire. Oh well, I’m thrilled to be back in business using my paperwhite. I super appreciate your help!

If you're all set, you can close the issue.
