Answer 1

Are you sure you're installing it an not uninstall it or something? I would try downloading a fresh copy of eclipse and try installing it onto that

Answer 2

It's happened to me as well, though I'm on Linux, not Windows (but it was also Eclipse 3.5.2). I uninstalled Eclipse then reinstalled it and the first thing I then installed was Android SDK. It now works well.
