I want to use the usepackage siunitx for my thesis (scrreprt). MikTeX asks for installing the documentclass beamer each time when I compile my document (and then freezes while installing). When I cancel the installation of the beamer package, the document is compiled correctly and displays the correct number with SI unit.

Here is a small example:


How can I avoid the installation message? It does not affect anything, it is just annoying.

Thank you!

No problem here with current MiKTeX 2.9. Which tex distribution and operating system do you use? I guess it is outdated, perhaps TeXLive 2009? – Kurt Sep 26 '13 at 9:38
Run your editor as an administrator. – percusse Sep 26 '13 at 9:40
I am using MiKTeX 2.9 with TeXnicCenter, and unfortunatelly it does not work even if I run it as administrator – Dani Sep 26 '13 at 10:23
What happens if you force miktex to install beamer separately (by trying to compile a beamer document)? – T. Verron Sep 26 '13 at 11:29
It freezes...I tried this also using the package manager, but there is some problem with beamer. And I do not know why I should need beamer for the siunitx package, they do not seem to be related in any way. – Dani Sep 26 '13 at 13:21

It seems that you have a problem with your installation of MiKTeX, if it is the current one. I guess you have installed basic MikTeX? See the first line of your log file. Do you see This is pdfTeX, Version 3.1415926-2.5-1.40.14 (MiKTeX 2.9)?

If no, you should update.

If yes, your installations is faulty.

Try to reboot your computer. Do you still have the error? If Yes follow this:

  1. Delete the old installation completly! including TeXnicCenter.
  2. Download the installer for complete MiKTeX from http://www.miktex.org
  3. Install complete MiKTeX
  4. Download TeXnicCenter from http://www.texniccenter.org
  5. Install TeXnicCenter. It should recognize that you have an installed MiKTeX.
  6. Now compile your MWE 3 times. It should run. If not, you have a problem with your computer.

Edit: I compared your file list with mine. You are using old packages for siunits and expl3.sty. My File List says:

 siunitx.sty    2013/07/31 v2.5s A comprehensive (SI) units package
   expl3.sty    2013/07/28 v4582 L3 Experimental code bundle wrapper 

and you have version 2.5q (older) and v4469 (older). Please use the MiKTeX package manager to update your packages.

Thank you for your advice - I did a complete new installation of MikTeX and TeXniccenter. Unfortunately the error is still there. – Dani Sep 27 '13 at 7:53
@Dani just to be clear: the MWE you gave wants still to install beamer? Please add \listfiles before \documentclass, compile and add the part *File List* from your log file to your question. – Kurt Sep 27 '13 at 8:41
I added the file list. Yes, it still wants to install beamer. – Dani Sep 27 '13 at 13:23
