Problemer med wvware

Hej allesammen.

Jeg i øjeblikket igang med at skoleprojekt, hvor en del af projektet går ud på at uploade word dokumenter (.doc), hvorefter det skal konverteres om til html. Til dette problem har jeg fundet "programmet" wvware (http://wvware.sourceforge.net/) til at konvertere word dokumenterne. Herudover har jeg fundet følgende stykke phpkode der implementere wvware i min webside:

     /* Usage - call base URL and add wordconv.php?name=xxx where xxx =  
       filename of .doc file to be converted (without .doc extension)
       For example: 
       http://mydomain/mydirectory/wordconv/wordconv.php?name=try
       to convert try.doc in mydirectory
       * Create a subdirectory called wordconv and make it readable and 
         writable by the web server (aka php) process.
       * Put this script into the wordconv subdirectory.  The parent
         directory should contain the .doc file.
       * To prevent a security problem make this script read only to the
         web server process.
       
       This script will create all .html, .png, etc. files in the wordconv 
       subdirectory.  The .html files will not be deleted after serving.
       The created html files are reconverted when the modification time 
       on the .doc file is newer than the .html file.  If the .html file
       is already present, it is served up directly (i.e. cached) without
       reconversion.

       Requires: 
       PHP - http://www.php.net
       wvWare - http://wvware.sourceforge.net

       Note:
       Change the path of wvWare in the $wvware variable below to match
       the path of your wvWare executable.

       Revision History:
       v1.01 15 Jan 2002 Moved the script to the wordconv subdirectory
                         to ensure that URL for created graphics is correct.
       v1.02 30 Jan 2002 Add a sanity check to ensure that the wvWare
                         executable is present and executable.

    /* Where is wvware installed?  Command line options? */
    $wvware = "../../../wvware";
    $wvware_options = "-d";
       
    function updateword($wordfilename, $htmlfilename) {
        global $wvware, $wvware_options;
        $htmldir = dirname ($htmlfilename);
        /* ensure that we get any images into the html directory */

    $wordfilename = $basedir . "/../" . escapeshellcmd($name) . ".doc";
    
    $htmldir = $basedir . "/";
    $htmlfilename = $htmldir . escapeshellcmd($name) . ".html";

    if (! file_exists($wordfilename)) 
        die("Unable to open file $name ($wordfilename). Set URL variable " .
            "?name=xxx to the base filename of the word file (e.g. try " .
            "for try.doc).  Do not include path!  This script should be in " .
            "the wordconv subdirectory to the .doc file.");
    if (! is_dir($htmldir))
        die("Directory $htmldir does not exist.  It must be " .
            "created and readable and writable by your web server.");
    if ((! is_writeable($htmldir)) || (! is_readable($htmldir)))
        die("Directory $htmldir must be readable and writable by your " .
            "web server.");
    if (file_exists($htmlfilename) && (! is_writeable($htmlfilename)))
        die("The html file ($htmlfilename) exists already but is not " .
            "writable by the web server.");
    if (! file_exists($wvware))
        die("The wvWare executable file $wvware cannot be found.  Please " .
            "ensure that the \\$wvware variable in the script is pointed " .
            "to your wvware executable.");
    if (! is_executable($wvware))
        die("The wvWare executable file $wvware is not " .
            "executable by the web server process.  Please change the file " .
            "permissions to make it executable.");

    /* Do the work */
    if (file_exists($htmlfilename)) {
        /* Do we need to update the html file? */
        if (filectime($wordfilename) > filectime($htmlfilename))
            updateword($wordfilename, $htmlfilename);
        else readfile ($htmlfilename);
    }
    else  updateword($wordfilename, $htmlfilename);

I behøver ikek at læse det hele igennem, men blot at se på et af de sidste "if"-udtryk - det der hedder:

 if (! is_executable($wvware))
        die("The wvWare executable file $wvware is not " .
            "executable by the web server process.  Please change the file " .
            "permissions to make it executable.");

... fordi det er her den går galt. Jeg HAR lavet wvware biblioteket executable (samt readable og writeable (chmod 777, tror jeg nok det hedder)), men den melder stadig fejl!

HVAD ER DER GALT?!?!

Jeg vil meget gerne have hjælp.
