VBSScript FTPUpload not working

I've been looking for solutions to the error I receive, when using the FTPUpload.VBS program integrated in PDFCreator.

I want to upload my created PDF files after I have saved them to my local drive to an FTP location (automatically).

I found some posts, that this may be to do with IE7 or IE8... but since Vista's and 7's are by default installed with one of these two - I have a bit of a problem.

Are there any solutions, other than installing ChilkatFTP or ASPFTP to make another script ?

Kind regards,
