I installed Strawberry Perl / swftools / imagemagick, commented the line use 5.012 and ran it:

c:\strawberryperl\perl\bin\perl.exe dopuzzle.pl http://five.flash-gear.com/npuz/puz.php?c=v&id=4642644&k=86817760
"montage" failed to start: "De ingang is ongeldig" at dopuzzle.pl line 54.

("De ingang is ongeldig" would be translated to something like: "the entry is invalid")

(FYI: a new directory is created in the temp directory and I see that thousands of small images are created (which looks to be parts of the puzzle - after montage fails, these files are cleaned out)

Any idea?

I made a fork of the original with updated code that works with all the puzzles, has an user interface so you dont need to manually change the code and has an easy installer

If you get the error about the --outputformat parameter, change line 41 to:
system swfextract => '-j', $id, '-o', "$dir/$id.jpg", $swf;

For me, it opens a DOS box that disappears much too fast after I clicked on the .pl-script.
Also no chance to tell pearl any paths.
But I couldn't find a jpg anywhere in the folder.
