I understand where they might be useful; that is why I am using one. But my
experiments show that a failing launch condition during uninstall from ARP
always shows the fatal error message after displaying the launch condition
message.
Which leads me to your suggestion regarding the custom action that I run. I
have it set such that the return value is ignored. The CA is scheduled to
run before the launch conditions and it merely sets a property that is
evaluated in the launch conditions.
As a test, I have taken out my custom action, changed the launch condition
to fail on uninstall and I still get the fatal error.
As I mentioned earlier, I also used the SampleFirst package from the
tutorial, created a launch condition that fails on uninstall. It also
displays a fatal error dialog when uninstalled from ARP.
I can only conclude that launch conditions are not meant for uninstalling.
But I would sure like to be proved wrong as my boss is putting a lot of
pressure on me about this issue.

If you determine that you need some prerequisite to successfully
uninstall.

You can't show authored UI because ARP runs the uninstall in basic UI
level. I assume your objection is just to the error message? You can try
a custom action that returns ERROR_INSTALL_USEREXIT to see if ARP shows
a different message in that case.
