Issue: When I double-click on the Mac dmg installation file, nothing happens – the program launches then disappears

This can occur for any of the following reasons:

  1. A firewall is preventing the setup file from running.
  2. You do not have the appropriate access rights – you need to be logged on as an Administrator to install the Viewer software.
  3. You have uninstalled the Viewer and have not emptied the old version from your Trash.  Make sure there are no copies of the Viewer installation in your Trash before installing a new version of Safeguard.
