Help Please! Calibre installed on wrong computer but not working on new one

AnnetteD · 02-23-2025, 06:12 PM

Please help. I have spent several days downloading 4,830 kindle books and my husband had 20 he downloaded to his. In my search for next steps, he jumped ahead of me and installed Calibre on his Windows 10 computer with dedrm and my Kindle serial number. Not knowing, I installed Calibre on my Windows 11 computer with dedrm and serial number to discover that it didn't work, my initial test does not open any books only shows the cover. I had him uninstall and delete the dedrm file and I did the same, followed by a windows 11 update and reinstalled to see the serial number was still there and with the same issue. My Windows 11 computer needs to be the primary, as I have downloaded all the books, because I am the reader. How do I resolve this challenge? Thank you in advance. Currently, I have one kindle.. as for some reason Amazon saw fit to deactivate my older one, I learned last night. Please

Thank you.

Which version of DeDRM were you installing. I would strongly suggest using the version at the Autorelease/Release page under Assets. Unzip the downloaded .zip file and install the DeDRM zip file.
