LyX ⇒ After update 2.3.0->2.3.4.4: Article.cls not found

[LeFish]

Hi there,

today I decided to update Lyx because often crashed after closing Acrobat Reader, which I used to view the output file.

Anyway, I now have the problem, that Lyx does not find the document class article.cls, which I used in my document. The error is as follows:



Opening the very same document in version 2.3.0 worked perfectly fine.

My Latex preamble is as follows:

Code: Select all

%Erweitertes Unterstreichen
\usepackage{soul}

% verschieden Symbole, Zeichen wie (c), €
\usepackage{textcomp}

\usepackage{ %a4wide,
            ellipsis, fixltx2e, mparhack,   %Fehlerkorrektur für Marginalien

}  

% schönerer Blocksatz!!

I already did a MikTex update and made sure, that ltxbase is installed as suggested in this post: https://latex.org/forum/viewtopic.php?t=28642

Can you help me please?
Thanks in advance!

Best regards

Hi there,

As I had the same problem after reverting to 2.3.0, I found the following post: https://tex.stackexchange.com/questions ... -available

As it is suggested I did a "Tools > Reconfigure" after installing the needed packages in MikTex. I suppose you have to do this, whenever you install new packages in MikTex.

Now it works on 2.3.0 and 2.3.4.4!

Best regards,
LeFish
