UmmyVideoDownloader Loader dialog progress bar shows 100% then remains open. Program not installed. Dialog then shows Couldn't download extension files, try to download from the website, with a button. Button downloads the same installer file still doesn't work. With dialog progress bar showing 100% mouseover starts the process over, but it never completes
