Copyhello

I've made a video of a wedding.  I need to give it to others so they can watch it on their computer. I have tried to copy the wedding to a USB stick.  It didn't work on friends computer... Chuck. It's in too hard basket....better get it out. Ha ha. 

I made video in movie maker if the perso I want to see the video... Wants to view on their computer ...would they download. Movie maker and then be able to see it. Or do I alter what programme I save and copy it to.

sorry for long question.  I would be grateful for any advice on how to get it to wedding party so they can view the movie.

thanks so much
