I just upgraded my Miktex distribution and I am not able to compile my MNWE example (see below)

  % tex.stackexchange.com/questions/12703 
  \usepackage{colortbl}   % comment this line before compile
      \(a + b\)  & first equation description    \\ %\midrule
      \(a - c\)  & second equation description   \\

When I comment line with \usepackage{colortbl} then everything works fine. It seems that I have same problem discussed in question: new array.sty and colortbl.sty incompatibility?, but this question is dated 2018-04-30. I've updated my distribution every month. I'm not able to find out where the error is.

 *File List*
 article.cls    2018/09/03 v1.4i Standard LaTeX document class
  size10.clo    2018/09/03 v1.4i Standard LaTeX file (size option)
   array.sty    2018/11/13 v2.4j Tabular extension package (FMi)

   color.sty    2016/07/10 v1.1e Standard LaTeX Color (DPC)
   color.cfg    2016/01/02 v1.6 sample color configuration
  luatex.def    2018/01/08 v1.0l Graphics/color driver for luatex

I don't understand why I have colortbl.sty with version 2012/02/13 v1.0a. It seems to me, that update process in Miktex didn't work properly in my installation.

In next step, I try to look into installation folder and I am really surprised, because package colortbl is placed in:

  • c:\Users\HP\AppData\Roaming\MiKTeX\2.9\tex\latex\colortbl\colortbl.sty

and also

  • c:\Program Files\MiKTeX 2.9\tex\latex\colortbl\colortbl.st

I guess I discovered the wheel again .... Can I delete ..\AppData\Roaming\MiKTeX folder?

    There was a bug in colortbl or code redesign recently. Try to update more than once a month. – user31729 Jan 6 at 18:58

    Your example runs for me with colortbl activated, in Linux with TL 2018, daily updated. Adding \listfiles just before \begin{document}, I get (amongst other entries) colortbl.sty 2018/12/12 v1.0d Color table columns (DPC), i.e. the latest version is from 2018/12/12 – user31729 Jan 6 at 19:40
  • Compiles for me. Did you update as user and as admin? – Ulrike Fischer Jan 6 at 20:45

    As mentioned, both your array (current: v2.4k; yours: v2.4j) and colortbl (current: v1.0d; yours: v1.0a) packages are out-of-date. – Werner Jan 7 at 18:54
