I updated to the April 2018 windows 10 updates and my ant video downloader worked fine afterward. I also updated gom player and the bing search engine caught a ride onto my computer and the only way I could shake it off was to uninstall firefox and reinstall it. I had to reinstall the ant video downloader and I found the native application wizard wouldn't open. I mean the native application would download to my browser but when I clicked the blue arrow to install it nothing happen. I finally was able to install it by clicking on the folder right of the setup wizard in the browser, and the setup wizard in the folder opened, I was able to reinstall it that way..
