I dont understand your problem. The Mill Wizard does not ask anything about users. Do you mean you right click the icon and ask it to run as admin? That should not be necessary, after installing the wizard just click on the icon and run it as the user you are logged in as.
The wizard does not use any INF files. Do you mean INI file?
To follow the Microsoft conventions we made the wizard load load files using the environment variables. When the wizard runs the first time it silently moves a couple files into the users space. This only happens the first time it runs.
