I set a bunch of different Properties depending on what is not-installed
and then display one dialog that lists all missing pre-reqs. I don't
care to show them the ones that are already installed, just those that
aren't.

Subject: Re: [WiX-users] Making a Requirements Dialog
I guess that's one way. It just seems a little unintuitive to show
pop-up
dialogs for the requirements. I thought about this for a little while
and
came up with another method. Create one dialog with all of the possible
requirements if every feature was selected and selectively gray-out the
ones
that don't apply (using enable/disable Conditions). Then, show green
check-marks if the non-grayed out requirements are met, red X's if
they're
not. Although the interface might look a little cluttered with a lot of
grayed-out items, this seems to be the easiest to do with WiX.
