I am running Lyx 1.5.7 on Windows XP SP2 with MiKTeX 2.5 installed.
This is most probably the reason.
Before you proceed fiddling around in your system to find the
misconfiguration, I recommend to
1. uninstall LyX _completely_
2. uninstall MikteX 2.5 also _completely_ (MiKTeX 2.5 is too old and
thus not supported by the MiKTeX developer)
3. uninstall Imagemagick (if installed)
4. uninstall Ghostscript (if installed)
5. open an Interent connection
6. reinstall LyX 1.6.5 using the complete version of this installer:
http://wiki.lyx.org/Windows/LyXWinInstaller
This will install MiKTeX 2.8 and also all LaTeX-packages needed by LyX.
It also installs an up-to-date image manipulation system (Ghostscript,
ImageMagick, etc.).
