Did you set you try telling it NOT to ignore the return value since you want
it to fail if the condition fails, and returning the value
ERROR_INSTALL_USEREXIT from the CA when it fails?

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.
