Unless you've customized your installation, when you compile your 
document with MiKTeX 2.6 it will use the packages installed in your 
MiKTeX 2.6 directory and ignore those in your 2.2 installation. The 
packages installed with 2.6 are the latest (or nearly so) versions from 
CTAN. The ones installed with 2.2 are not, unless you've been updating 
them yourself by hand. So when you switch from 2.2 to 2.6 you *are*, in 
fact, upgrading the packages you use.

I can reproduce the error, but your example is far from minimal. Here is 
the sort of thing people are usually after when they request a minimal 
example:

\documentclass[a4paper]{ifacmtg}
\usepackage{harvard}
\listfiles
\begin{document}
   \cite{STA_1995}
   \bibliographystyle{ifac}
   \bibliography{bibliographie2}
\end{document}

This reproduces the error without introducing all sorts of unrelated 
material that make solving it more difficult. It appears that there is a 
clash between ifacmtg.cls and harvard.sty. If you remove harvard.sty, 
ifacmtg.cls will automatically load natbib.sty; however, a clash remains 
and you get a different error. I suspect ifacmtg.cls needs to be patched 
or updated to fix the problem.

Hope that helps.
