For 7 hours I was downloading a 12.9 GB file and finally, on the home-stretch at 46 minutes to go, download speed much faster than before, it says it is finished, then when I go to click on it it says it is invalid. I've been having this same problem since after my Windows 10 reinstall a week ago. Please help, it's every day I'm having horrible computer troubles and it seems to be a lot worse after a brand new Windows install, it's a different problem each day. I understand computers are not perfect but do people really have this large amount of issues?
