This application doesn't need to install, so launching it works fine. All features, so far, work fine. When you first start it, it seems to be in German, but this is easily fixable by clicking Preferences and then the British flag. :)
There is one issue, though. Since there is no installation, it forgets your RapidShare login and Language choice when you exit it. They are easily changeable though so it's not a big deal. :)
