[Tex/LaTex] After failing to install media9, removing package from preamble continues giving error Support package l3kernel too old

media9miktex

I tried to install media9 by putting the following code in the preamble: 

\usepackage{media9,graphicx}

This in order to be able to add sound files to my pdf, as this guy also asked help about.

When compiling the pdf, I got several errors:

  • Support package l3kernel too old.
  • File ocgbase.sty not found.
  • You have requested, on input line 48, version 2016/03/26 of package expl3, but only version 2015/11/04 v6224 L3 programming layer (loader) is available.

I tried fixing this be reinstalling MikTex, by synchronizing MiKTeX package manager, and by running a MiKTeX update, but none seemed to work.

Thereupon I decided to delete 

\usepackage{media9,graphicx}

from the preamble, but I still get the same error messages (including the one that I request something on line 48, which I don't) and cannot compile pdf's at all. What should I do to make the software know that I don't want to run/install l3kernel and ocgbase? I can't continue my work like this.

I use MiKTeX 2.9 and TeXstudio 2.10.8. This is my preamble now, although I can hardly imagine it to be of any help to anyone:

If I open other .tex files and try to edit & compile those, I get te following error:

  • Could not start the command: "C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\xelatex.exe" -synctex=1 -interaction=nonstopmode "stories".tex

Best Answer

Thanks for the help. In my case I had to change the two dates in the xparse.sty and in the l3keys2e.sty from (2016/03/28) to (2016/03/26). 

\RequirePackage{expl3}[2016/03/26]
\@ifpackagelater{expl3}{2016/03/26}

This is a quick solution for one or two installations, but not for more.
