I will try to apply the patch, but in the meantime I may have discovered some pertinent information. On Windows XP there is a DOS-style command called "convert" which can be accessed inside a command-prompt window. I wonder if there could be a conflict or confusion with this module?
  c:/WINDOWS/SYSTEM32:
  total used in directory 495476 available 13243296
  -rw-rw-rw-   1 XXXXXXX   root           333 2001-09-12  $ncsp$.inf
  -rw-rw-rw-   1 XXXXXXX   root           860 2002-01-27  $winnt$.inf
  drwxrwxrwx   1 XXXXXXX   root             0 12-28 07:32 .
  drwxrwxrwx   1 XXXXXXX   root             0 12-28 14:25 ..
....
  -rwxrwxrwx   1 XXXXXXX   root         13824 2001-08-18  convert.exe 
....
The way I found this out was that I tried the ImageMagick test in a command window : "convert logo: logo.gif" and got an error instead. When I navigated to the ImageMagick install directory using a DOS-style "cd" command it worked. If you append the ImageMagick directory to the end of the "PATH" environment variable the MS Windows "convert.exe" will be found first.
