I have the same experience. I tried this a week ago, and then again today with the latest download. Running as admin makes no difference. The install completes, but on startup TurboTax shows a white window with TurboTax in the title bar, then nothing happens (CPU usage zero). I'm on a regular laptop (Dell XPS) and don't have problems with other software. I can only think this is a TurboTax problem.
