For years I have delivered pdf files with links to xls files. Clicking the link opened the file. Now I get a security message, then a message that the file cannot be found, and then a message that the file cannot be opened.
When I check the link properties the pathway is correct.
I know that for security reasons Acrobat will not launch an application that requires an .EXE but I was, until today, able to open an xls file. I use Acrobat Pro 8.2.4 and Windows XP.
