I forgot to mention that it is also a Mac.
Thanks for the response Pat.
I tried opening it up, but the same thing happened. As soon as I click on open, "The application Install Adobe Flash Player quit unexpectedly" appeared right away
What version of Mac OS X do you have? If it's 10.5 or older, Flash Player is no longer supported on it and could explain why it quits in that fashion. If you do have 10.5 or older you'll need to install version 10.3.183.30, the last supported version for OS X 10.5. An archive file containing the 10.3.183.90 OS X installer is available from the Archive Flash Player page.
