Not Useful

I am not tech savvy and thought this should be an easy fix for a google docs video someone sent me. I downloaded the app and converted the video according to the icon for apple products. It converted my file but won’t play on my imac because it says I need version 7 of Quicktime. I have version 10pointsomething.

name-already-taken about Total Video Converter Lite, v3.6.1
