Most likely a simple question here. How would you abort a silent install in a Basic MSI setup based upon a property setting filled in by a custom action? I know the Abort keyword does this in InstallScript, but what is the MSI way to do this?
There is a type of custom action called "error" by InstallShield which is Custom Action Type 19. That action shows a message and end the installation. I guess it won't show a message in silent mode and will just end.
