We have an issue with PDF geeneration and as per the solution, we have uninstalled the existing PDF Xchange 3.0 and reinstalled from the links available in QlikCommunity.
After installation, when the pdf is generated there a mark generated by PDF Xchange as it is a trial version. Attached is the screenshot. Please could you let us know where can we get eh licensed version for QlikView.
Make sure that you are using the PDF_Xchange for you publisher only, and make sure that your publisher LEF has "PDF_GENERATION;YES;;" and also if you using it for you local machine, this watermark will show, because like I said it is only for the publisher. If you doing as I mention above, follow Bill's comment.
