Just got the FSX deluxe dvd. It won't install. The installer starts to go through its routine and then finally fails to a 1628: Failed to install error message. I've gone to the installshield site and downloaded their most recent installer, went to Microsoft and downloaded their most recent installer, and it hasn't made any difference. I've googled and noted a few other people with this error but no real solution. Any suggestions--short of reformatting--would be very welcome. I have winXP.
