There is another company also called PDF Creator (www.pdfcreator.fr, www.pdfcreator.es) that falsely claims to offer a free download (téléchargement gratuit) on its website, likely to be passing off as the original and free/open-source PDFCreator. Their software is not free.
Beyond deceptive claims, they use advertising material that is almost identical to PDFCreator. Please see the advertisement below (right-hand side is PDFCreator, while left-hand side is the imitation).
The company is based in Canada (PDF Pro Software Inc. - www.pdfpro.com) and Hong Kong (PDF Pro Limited). The founder of the Canadian company is listed as Edmon Moren, while the sole Director in Hong Kong is Guy Facey, a lawyer with Facey & Associates.
