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
