Hello techies, I had the same problem with acer finger print sensor when i installed 7 a week ago. The pre installed drivers did not work, so i downloaded a 100 MB file from acer website. Unfortunately, it still didn't work. Although, it works perfectly on my XP.
You should have posted this in a new thread.

However, are these the drivers you downloaded?

They are supposed to support Vista (both 32 and 64 bit versions), so they might work in 7.

All that I can suggest is running the installer as administrator, in Vista compatibility mode.
