I was fooled into beleiving that what ever app in Apple store has been tested. This does not work

I am new to Apple MAC. I was looking for app to run my .wmv files. I saw this app and believed that it was good from the description; every app on the apple store was tested before placing it there, and even putting a price on it. I did not see the Caveat by those who purchased the app before. The app did not work. it only came to my tray and veneer displayed the video it was supposed to play. This is fraud app, and should be removed from the apple store.
