That does not make sense, there should be no user in program files unless you added something yourself.
Is there a directory in Program Files you created that you are trying to install to? Need some more details as to where this apple!!!! thing came from.

Go into Control Pane, User Accounts, click Manager User Accounts, what is showing up there?
