My tester flagged as a bug the installer's showing "unknown" for the application size. I tried out several other installers (Opera, ScreenShare, HandyTaskMan) and found that they all do the same thing -- in the application information window displayed by the installer, "Application Size" is always "Unknown".
Is this a known problem? Is it a function of having multiple language resources as part of the package? Anything I can do in my package file headers or elsewhere to encourage the installer to display a useful value for application size?
