Google Winrar, the website should be something including the term "rarlabs" or something to that effect.

Try 7zip, its free.

www.rarlabs.comWinzip won't open rar or 7zip filesWinrar is shareware, that means after 30 days it nags you to pay for it, but whether you do or not is entirely your choice; it will not stop working.7zip is completely free.
