side caption on beamer poster [closed]

Question

I like to write caption on the side of the image in a poster using Beamer. I write something like the below. But it doesnt work. It show me a error message:

texify.exe: Windows API error 32: The process cannot access
the file because it is being used by another process.

texify.exe: Data: 1.log

Could any one tell me, how to solve this problem?

\documentclass[final]{beamer}
\usepackage[margincaption]{sidecap}

\begin{document}

\begin{textblock}{}[0,-2.5](33cm,0cm)%
\begin{varblock}[43cm]{}

\begin{SCfigure}
  \centering
\includegraphics[height=10cm]{Figure/Panorama_LB.jpg} 
  \caption{ ... caption text ... }
\end{SCfigure}
\end{varblock}
\end{textblock}

\end{document}
