For All the "DeDRM Isn't Working!!!" Posts...

[ownedbycats]

The currently maintained version of the DeDRM plugin for calibre can be found at NoDRM's github repository:

https://github.com/noDRM/DeDRM_tools

The version number at time of writing is 10.0.3


Original post:

Spoiler:

Calibre 5.x requires DeDRM 7.1.0 or later
Calibre 4.23 requires DeDRM 6.8.x

DeDRM 7.1.0 mostly works OK. If you come across a book for which it doesn't work, drop back to 4.23 and 6.8.x. Here's a method that lets you run 5.x and 4.23 side-by-side on Windows:

1. Grab an older version of Calibre Portable.

2. Extract it wherever.

3. Exit your main Calibre beforehand. Open Calibre Portable.

4. Install the DeDRM plugin.

5. Copy your settings (C:\Users\[User]\AppData\Roaming\calibre\plugins\dedrm.json) over to [PortableInstallationFolder]\Calibre Settings\plugins\ so that the keys are available.

6. Now there are two options from here.

OPTION ONE (Best for small libraries with few plugins):

a) Open your current library in Calibre Portable. Only do this on 4.23 as otherwise the databases aren't quite compatible with 5.x. (Note that since the portable version is 32-bit, it may have difficulty with very large libraries.)
b) DeDRM your books.
c) Close Calibre Portable. Open your main Calibre.
d) Enjoy your DeDRM'd book.

OPTION TWO (Best for larger libraries with multiple plugins):

a) DeDRM your books.
b) Exit Calibre Portable. Open your main Calibre.
c) Use Add Book. Navigate to your Calibre Portable's library and add the eBook file.
d) Enjoy your DeDRM'd book.

Hope this cuts down on the number of posts made about this.

THis is exactly what I am going to do once I install Calibre 5.x.

It wouldn't surprise me that much if calibre portable worked in wine on Linux.

5. DeDRM your books.

6. Exit Calibre Portable. Open your main Calibre again.

7. Use Add Book. Navigate to your Calibre Portable's library and get the file for your DeDRM'd book.

Hope this cuts down on the number of posts made about this, at least until a compatible version is available.

Plan B:
Use older version of DeDRM that still works as standalone application.

not working, it did let me install the prior version. The plug in however does not even allow you to upload ...Luckily I have a prior version on my other desktop

Wish I'd have seen this before upgrading -- I wouldn't have upgraded yet -- no rush here.

EDIT: Looks like the library was compatible, so it was easy to roll back. I've removed it from my homebrew install and manually installed for now to avoid future unwanted updates.

You can downgrade back to 4.23. The installers are all available on Fosshub from the first post.

I take it this means The Tools will not work in Calibre 5? Just downloaded but haven't installed it yet. And is anybody running it on Windows 7? I've been using version 4.13 which is not supposed to be Win7 compliant but so far have had no issues. Gonna get me an older backup version just in case.

I just wanted to point out that Kovid's official download page for older calibre versions is at:

https://download.calibre-ebook.com/

Thanks. I forgot about that.

Or downgrade to 4.23.0. Not really anything in 5.0 that interests me right now.

Thanks all. I've downgraded to 4.23 and reinstalled the plug in but it still doesn't work. Do I have to uninstall the 5.0.0 version as well? I now have two versions of calibre on my laptop.

That's odd, downgrading shouldn't result in two Calibres (unless you grabbed a different bit-version).

The 4.23 version is 64 bit. The 5.0.0. I don't know. Do you think it's safe to delete the 5.0.0. version, and I won't accidentally delete the whole of calibre?
