Read this and tell me if it solves your problem: https://www.romulation.org/forum/index.php/topic,3880.0.html

"as it is not a torrent file" .....? sounds like file associations are screwed,or you need to download winrar.

Right click, Properties, Open With and choose WinRar etc. And then extract it. You can still extract it without doing this, but better to fix up your associations.
