Can’t watch videos on laptop it keeps saying download apple application support?

I got a new camera for christmas and I took some videos of my daughter with the intention of uploading them to the computer, deleting them off my SD card, and making room for more pictures.

Well, whenever I try to play the videos it comes up with either “unknown format or broken link” or “apple application support”.

where do I download that? or are my videos lost forever? ):
