    Why does "Install Adobe Download Assistant" keep failing to run or install on my Mac Pro OS Lion 10.7.5


      I get the following message when trying to run the download assistant:

      The application cannot be installed due to a certificate problem.  The certificate does not match the installed application certificate, does not support application upgrades, or is invalid.  Please contact the application author.
