I have exactly the same problem as clamon when trying to install drivers for the leonardo on my windows 7 64 bit machine.Have also tried installing on an old xp laptop and this worked fine.But I need to get it working on the windows 7 box.Any ideas?
Windows still does not find a driver.

At the bottom of the IDE screen it says 'Arduino Leonardo on COM1' but when uploading a sketch it doesn't find the board.
Confirming what Clamon and others have said, there does seem to be an issue with Leonardo drivers on a few specific models of Dell and, apparently, HP laptops. I'm working with one community member now to track down the bug and hope to have a fix soon.
