I don't have easy access to this setup, so cannot easily test this.
However, I'll try to help you do tests that may help diagnose
exactly what is going wrong.

After this error, the next one is not surprising ...

   ... since  ./images.tex  will not have been created yet.
Presumably the command whose syntax is supposedly bad is
(one step along the path) involved in creating  images.tex .

The place that you want to examine is here:


sub preprocess_images {
     do {
         print "\nWriting image.pre file ...\n";
         open(ENV,">.$dd${PREFIX}images.pre")
             || die "\nCannot write '${PREFIX}images.pre': $!\n";
         print ENV &make_latex($latex_body);
         print ENV "\n";
         close ENV;
         &copy_file($FILE, "bbl");
         &copy_file($FILE, "aux");
         local($num_cmds, $cnt, $this, @cmds);
         @cmds = (split ('\n', $preprocessor_cmds));
         $this_cmd = $num_cmds = 1+$#cmds;
         $cnt = $num_cmds; $preprocessor_cmds = '';
         while (@cmds) {
             $this_cmd = shift @cmds; last unless ($this_cmd);
             $this_cmd =~ s/.pre /.tex$cnt / if(($cnt)&&($cnt <  
$num_cmds));
             $cnt--; $this_cmd .= $cnt if ($cnt);
             $preprocessor_cmds .= $this_cmd."\n";
             L2hos->syswait($this_cmd);
         }
         # save pre-processor commands in a file:  preproc
         open(CMDS,">.$dd${PREFIX}preproc")
             || die "\nCannot write '${PREFIX}preproc': $!\n";
         print CMDS $preprocessor_cmds ;
         close CMDS;

     } if ((%latex_body) && ($latex_body =~ /newpage/));
}

This is at ~ line 3729 .
The line number may change a bit with version and installation.

You can see the first  print  message.
The operating system calls come at the  syswait  command,
within a loop --- in case there is more than one step involved.

All the commands should have been written into a file,
named   preproc .

Can you find that file for your job ?
It should be in the subdirectory where the pages are being built.

Try executing the lines in there, one at a time.
What happens ?
It should either:
    (i)  work just fine;
OR
    (ii) give that message about a syntax error.


If (i) then we need to find an explanation for it not working
within the LaTeX2HTML job, even though it works manually.

If (ii) then either:
   (a) there is some syntax used by XP that isn't the same as for DOS;
or
   (b) latex2html  didn't install correctly under XP, at least for you.


Note that the version of LaTeX2HTML that you are using was written
before XP was available as an operating system.
So it is quite possible that you are testing portions of it that
have not been run before in this setting. That's unlikely, but
nevertheless possible, as LaTeX2HTML was developed primarily to
be a Unix tool. That it works at all under Windows is due to other
developers, who may not have tested all the possible aspects.

It's not relevant yet, but may become so when we get past the pre- 
processor
problem.

Even so, those Perl files should still be executables.
What messages, from the installation procedure, led you
to mention them here ?


Hope this helps,
