Today I decided to install "PDF Converter Ver. 8" from Nuance.
My intent was to convert some PDF book files to MS WORD files.
Then add to Calibre.
That worked on one test book and Calibre converted the book to ePUB format.

But when I went to compare the appearance of the new ePUB version versus the old PDF version I found that clicking on "View" in Calibre mistakenly "Added" the book.

I have since;
Uninstalled PDF Converter.
Uninstalled Calibre.
Re-installed Calibre.
Again uninstalled Calibre.
Again re-installed Calibre.

I am still unable to "View" any of my PDF books in Calibre.
"Viewing" PDF files results in "Adding" duplicate copies.
ePUB and MOBI files view correctly.
I have quite a lot of technical books in PDF format.

Can anyone suggest what I should do to view PDF books in Calibre ?

Any help for a senile old codger of 82 would be very gratefully received !
