HTML-Kit Tools does not read pdf files created with Arcobat 8 anymore, What can I do to manage pdf files?

If you're looking for a way to invoke Acrobat or other program from HTML-Kit project window, "Explore Item" option on the right click menu should help.
what do you want to accomplish by reading pdf files ?
