Document Classes ⇒ Beamer: `beamer.cls' not found

[haaj86]

Hi,

I have used Beamer class before on windows vista with MikTeX & TeXnicCenter. Now, I have windows 7, and I installed both Miktex and texniccenter, but when I try to creat a presentation as simple as:

Code: Select all

\documentclass{beamer}
\title{Example}
\author{haaj86}
\begin{document}
\frame{\titlepage}
\end{document}

I get the following error

Code: Select all

! LaTeX Error: File `beamer.cls' not found.

The Log file is:

Code: Select all

This is pdfTeX, Version 3.1415926-1.40.10 (MiKTeX 2.8) (preloaded format=pdflatex 2010.1.25)  22 MAR 2010 20:16

Thanks very much localghost. I followed the manual you suggested and found the MikTex Package Manager (which I didn't know it existed!) and installed the beamer package.

Cheers

Hello haaj86 and localghost,

some time ago I could compile my beamer-presentations at my lap-top, but suddenly I get the reply `beamer.cls' not found. I have now installed the beamer package from the MikTex Package Manager as you two guys were saying (even if I believe that I have had it, maybe the people from my computer service deleted something when cleaning my machine), I have even refreshed the File Name DataBase and Updated Formats as I read at other fori. Still, I get the same reply `beamer.cls' not found. What should I do?
Thank you!

Hi lepijug,

welcome to the board!

This should have been all possibly necessary steps. Perhaps you need different install rights, since you could install as a user or as an administrator. You could post your .log file here, though I guess it would not tell anything about a possible beamer installation and location. Try kpsewhich beamer.cls at the command prompt, though I guess it won't be found.

Another possibility would be to install TeX Live, which works fine on Windows.

Stefan
