I guess the same thing happens with a file by Blizzard. They supply zipped 'Blizzard Downloader' (custom bittorrent thingy) on their Battle.net (http://battle.net) site to download game clients. The app won't run when extracted with Unarchiver, but it works fine with Archive Utility and BetterZip.

Because of copyright and stuff I probably can't upload the file itself, but I can send it to you if you want.
