    Can't install new version of Flash Player or uninstall old one.

    Mark Schaye1

      Mac OS 10.7.5 (64 bit)

      Flash Player version

      Mozilla Firefox 19.0.2

      When I try to install the new version, I get a message that says "only a single instance of this application can run", and when I click "OK", the install shuts down.

      I tried uninstalling the old version.  When I click "uninstall", nothing happens.
