I have a .pdf embedded as an object in an Excel Spreadsheet. I use a .pdf reader called Nitro PDF. I was told with their new version 6.x I would be able to configure so that their program would open the objects instead of adobe reader. It is unfortunately not a simple association issue as .pdf files are already associated with Nitro PDF. I have contacted their support but thought I would see if anyone here has a solution as I don't know how good their support is. Thanks!
