TuneUp Utilities 2003 has recovery as one of its features, I used it
and it works pretty good. Aslong as you havent written over the deleted file, you should be all right.
Unless there was a system restore with that file in it, your out of luck. Theres nothing in Windows that will allow you to get the deleted file, you
need need a special program. Why cant you just install it, and uninstlal afterwards?
