Also, is there an archive of old versions so I can figure out the latest version that works for me? Any help would be greatly appreciated. Thanks for a great plugin.

You may not what to hear this, but if you can, upgrade to 64-bit Windows 10. Less and less will work with Windows 7.

  "clipboard_copy": true, 
  "close_cb": false, 
  "github": true, 
  "is32bit": false, 
  "java_path": "java", 
  "last_time_checked": "2020-01-26 13:11:28.010000", 
  "locale": "en", 
  "usage": false
}

I changed the "is32bit" setting to true and ran it again. Still no results. Clipboard empty. I'm not sure if I posted the code correctly. These are my first posts here. Sorry. Thanks for your help

One quick question is what version of Java are you running?

Please open a Command Prompt window, enter:

java -version

and post the output.

If you're getting:

'java' is not recognized as an internal or external command,
operable program or batch file.

you'll need to re-install the latest Java version and restart your computer.

(AFAIK, the latest EPUBCheck version requires at least Java 1.8.0_152.)

java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)


Windows 7 64bit. I was using 32bit java. I installed 64bit java and the plugin still does not work. EpubCheck 0.1.3 works. Guess I'll go back to it or use the online tool. I really like the way I can go directly to any errors with the plugin.

Problem solved. After installing 64bit java and removing the plugin in calibre I deleted everything related to EpubCheck in my calibre configuration directory. Then, I reinstalled the plugin. It now works! Thanks to everyone for their help and thank you Doitsu for a great tool.

@boomdoggy: Good to hear you got the problem solved.

I think a note in the plugin should be added so wheb it's first run, it can tell people to install 64-bit Java on a 64-bit Windows.

Hi Doitsu. I've installed your plugin. How do I now check an epub using your plugin?

1. In Calibre, right-click a book and Select Edit book.
2. In Calibre Editor select Plugins > Run EpubCheck.

My old Windows 7 PC recently broke down and I have replaced it with a shiny new Windows 10 PC.

I have been rebuilding my set of software and learning about Windows 10 this last two or three weeks and have hit a problem I have been unable to fix.

Calibre and the plugins I use were almost the first things I installed.

Now I come to try and use Calibre and ePubCheck I keep getting the following error message.

I have tried reinstalling ePubcheck, Calibre and Java but nothing I have tried works (all the latest versions).

The version of ePubCheck in my installation of Sigil is working correctly.

My system Windows 10, with the latest versions of Java, Calibre and ePubcheck.

Any help would be appreciated

Thanks

1. Open the Calibre plugins folder (Preferences > Miscellaneous > Open Calibre configuration directory).
2. Double-click plugins.
3. Open EpubCheck.json
4. Change the following entry:

  "is32bit": false,

to

  "is32bit": true,

Thank you.

That was very easy. My struggles with Windows 10 getting things how I want them were not so easy.
Still I am learning which keeps me happy.

Hi, using EpubCheck 4.2.2 with Calibre Editor 4.18.
Getting a lot of DOCTYPE errors but Calibre Editor does not use DOCTYPE declarations.
Is it possible to fix it? Thanks!

If your book is an epub2 book, try changing the preamble in all html files to:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
  "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
