Bug in getmap?

Hi,

i just installed MiKTeX beside TeXLive to test my getmap package.
With some weird results. First it tries to use runscript.tlu from 
TeXLive to run osmimage. After goggleing, i learned that there should be 
a copy of runtexlua.exe renamed to osmimage.exe in \miktex\bin\
When i do that manually, i get:

osmimage: The Lua script is not registered.
osmimage: Data: osmimage

Does that mean that you can't manually install a lua script in MiKTeX?
In TeXLive it's possible with renaming runscript.exe -> osmimage.exe

Or just a bad interaction between my MiKTeX and TeXLive? Can somebody 
with a clean MiKTeX installation please test (with -shell-escape):

\documentclass{article}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage[overwrite]{getmap}
\begin{document}
\section{Example}
Do you want to visit the office of Dante e.V.? Here we go:

\getmap{Bergheimer Strasse 110A, 69115 Heidelberg, Germany}%
\includegraphics[width=10cm]{osmimage}
\end{document}

Thanks,

Josef
