I have a large number of books in pdf format.
I used to use Adobe Acrobat and when I clicked on a pdf book Calibre would open it in Acrobat.

I am now using Foxitpro as my default pdf reader and now when I double click a pdf file in Calibre I get a message saying, "The <Book Name> has no available formats."

I have tried going to 'Behaviour' and checking the box for Calibre to open pdf files in the Reader Pane, but that doesn't work either.

I am using Calibre V 3.44.0 and Windows 10.

Any help appreciated.

Thanks

Kevin
