installation stuck at 1%

The other day I tried to update Overwatch as I had not done so in a while but my game would not update at all. So I decided to uninstall and reinstall it to see if that would work. Well at this point in time I can’t seem to get the installation screen past 1% no matter what I do. I feel like I’ve tried everything to fix this but for some reason it will not download. I need some help.
