Hi Anne, First thing. Don't take the Microsoft message seriously. Just ignore it. Its just another of the numerous pointless messages churned out by a windows system. The software will be fine. Just continue through any prompts and install it. The reason you get the message is this... You will notice, in the Corel PDF Fusion feature list, they state... "Create new PDF documents from within any application that can print" To do this, the software installs a pdf file printer. This is just to be able to create a pdf file as though you were printing. It is a common way of providing a pdf export for applications. So, you have nothing wrong, just install and enjoy. Regards Les Hardy On 28/11/11 01:03, Anne DiStefano-Ring wrote: > PDF Fusion
