I have used DMPE 2 and would definitely recommend it. I have installed it on 3 computers(laptop, home computer and my office computer). Does not install on any more machines. I use GoToMy computer from home and dictate with DMPE 2 on my home computer and it works fine(with some quirks). Possible only 3 installs.

Hope it helps
