How do I convert an .MOV for use in Hitfilm?

Hello, I'm new! I have a short 1.5 min video that I like and want to make a music video with but it's an .MOV from an old Canon Elph 110HS and it wont load into Express. It says Install Quicktime. I have Windows 10. Should I install The last version of Quicktime, will it work, or is there a way to convert it to something usable?
