    Trouble installing latest Flash 11.4.402.278


      I don't know what I'm doing wrong in installing Flash Player 11.4.402.278. I have Windows XP 7, 32-bit, and use Mozilla Firefox. When I download, I save the file, although it doesn't show on Downloads list. It does show up, saved, in My Documents. The Run File box has shown once (I clicked yes), didn't run, so I left-clicked, got Run File, again clicked yes, and got "Only 1 single instance of this application can run". Since I've been trying, I then deleted the one other time the same downloaded file showed up in My Documents, so there's 1 file. Proceeded a step (got through Run file), then got "Certificate of authentication failed."  What to do? Thanks.
