X32 Edit V4.3 Mac osx 10.8.5. The downloaded app doesn't open?


Hello every body, warm regards from Atitlan at guatemala these is my first time writing. I have downloaded few times the edit app for mac V4.3 from my 2 different devices and None of the downloads open. They only blink, the finder window blinks too and... nothing happens. Can some one give me a hand with these please...

After some reading i have found that system requirements for the edit app are 10.7 or higher.
