Reinstalled OS, now can't install DRM plugin

[marp68]

Have done a complete reinstallation of Windows 10 on a new SSD. The I downloaded and installed the latest Calibre. Finally I imported back all data I had exported before reinstalling Windows. It seems to work well. I can open books, all personal ajustments are there, like My Shelves, my tags etc, reading settings, notations etc. I can also attach my Kobo and transfer without any problem.

But when I was going to install an unofficial plugin again, I got an error message. Does anyone know what went wrong?

It's the DeDRM_tools_6.3.4a plugin

That version of the DRM tools is not compatible with calibre 5.x. You need to get an updated version.

[marp68]

Aha, thanks.

There is only one more update from 2016. So would I have to install an earlier Calibre or do you perhaps know of any other DeDRM tools that works with the latest Calibre?

EDIT: I use it dor ADE books

[marp68]

Found this one and installed it. Will see how it works

DeDRM_plugin_7.0.0b4.zip

[davidfor]

It should. There is also a stickied thread for discussing exactly this problem.

[marp68]

And it did :-)
