Looking at the instructions on installing image magick on windows, I saw this:

NOTE: As of ImageMagick 5.4.8, the official ImageMagick windows installer includes PerlMagick for ActivePerl. Hence I will no longer be providing new binaries of PerlMagick from this site. The official distribution is available from http://www.imagemagick.org/www/windows.html

(PerlMagick == the Image::Magick module)
