What situations are they useful if they always show a Fatal Error dialog in
ARP?

I don't want to skip the launch condition as I put it there.  I don't want
users trying to uninstall while the program or Outlook are running because
it leaves files behind and this has been deemed unacceptable by our QA
dept.  This launch condition is not evaluated during install.

I am thinking of replacing the uninstall launch condition with a dialog that
has a Retry button allowing the user to close the program and continue.  Do
you think that is a suitable solution?

Fair point. Yes, it's probably not MSI showing the error but ARP. MSI
returns 1603 to indicate that the launch condition failed, which is
"fatal error during installation." Hence the error.

It depends -- they're useful in some situations. But you can always skip
a particular launch condition during uninstall by adding "Installed OR"
to those conditions.
