# problem with the new miktex updates

Anonymous created an issue

I would like to thank the authors of beamer for such a useful package. I use it everyday! Unfortunately, I cannot compile anything with the new updates in MiKTex files. I get the error message

Any solutions?

I have the same problem, I already looked in google but still no aswer to the problem.

Me too. After Miktex update, when I try to compile this minimal example using pdflatex, I get

! Undefined control sequence.

l.9 \end{frame}

<pre> \documentclass{beamer}

\begin{document}

\begin{frame}{First Slide}

Hello World!

\end{frame}

\end{document} </pre>

I'm using Miktex 2.9 64 bits, in Win7 64bit, and got the same error ! Undefined control sequence but the error appears only with the last update of Miktex, before that all my beamer files were working correctly. Hope someone in this forum could help.

I've found the solution in google, put this in the preamble:

\makeatletter\def\Hy@xspace@end{}\makeatother

Yes it's working now. Thanks

1. This was a passing issue with hyperref: this does happen, and is not a beamer bug.
