Hello all! I just purchased an Asus Vivobook 15 and installed PDFCreator and it does not work; any time I try to produce a PDF file I get a message that says "invalid driver". The troubleshooting utility says that to fix the problem I need to make PDFCreator the default printer; did it and it still does not work. I tried another open source PDF creating app and it also does not work. Tried Asus support and they won't help because of "third party applications". Anybody has seen this issue?
