I have the following problem:
I used Lyx 2.1.4 (with MikTex 2.9 ) under Win10 to edit my lectures.
Without problems until now. Just a few days ago I had undertaken an
unlucky attempt to use a newer version. Before the new installation I
have uninstalled the older one, but kept the installing "exe"-s.
The new versions did not work at all satisfactory and I decided to
return to my old version.
Easy done, but now I encounter something unexpected:
While importing "jpg" figures, they are shown within Lyx, but the
"pdf" or "eps" figures not ("error by converting in usable format").
Nevertheless, by "Document-show-pdf" they are shown correctly.
Analogously, export as "pdflatex" or "latex(pdf)" is OK, containing
all the figures.
This is no tragedy, bu a little bit nerving.
I have looked in the configuration at data formats and converter and at
missing packets, but did not remarked anything wrong.
Thanks for tipps!
