How to enforce to be opened by specified program after click the file link
 

The user created file link with a small icon display within a worksheet.
(ie. c:\test.jpg) When he click the link, it will be opened and viewed by
Internet explorer. But his computer default jpeg / jpg viewer has been set
to view by "AcdSee" program and also set program to related file type in
Windows Explorer.

Now how can I enforce that the jpeg file link should be opened by default
"AcdSee" program. (as printing photo in IE is not good)

Thanks!!
