I have a large excel index file, with a hyperlink to several thousand drawing files. The files are all pdf's, and when I click the link, they open in Adobe Reader only. I have Bluebeam set as my default program for opening pdf's. The only workaround I've been able to find is to uninstall Adobe Reader, so there is no choice but to open the files in bluebeam. I've had problems with a few files not being viewed properly in Bluebeam, so I would like to maintain Reader on my computer. Any ideas of how to get excel to use my default program when opening these links? Thanks in advance for your help.
