The installer runs in two phases: the UI phase, and the actual
installation phase. They are separate processes, and UAC is invoked
only in the middle (when it switches to the "server" phase).

It would well be possible to invoke UAC conditionally, depending on
what the UI phase learned.

Unfortunately, these are irrelevant, since they talk about UAC wrt.
applications. However, an MSI file is not an application, so all these
settings and APIs don't apply.
