Bug-description:
In an optional component (Get component state) I am copying some files that have to remain on the system even if the application is uninstalled.
If I install the application with this option selected, everything is fine.
If I install the application without this option, the files are missing. (Still ok).
But if I start the setup now again and change the option from unchecked to checked, installaware calculates the space needed correctly (exactly the size of the files) and starts working and finally says that the setup has finished, but the files have not been copied

It took me quite some time to find out what was going wrong and that it worked if I unchecked the 'Permanent File...' checkbox, but this not a solution I can live with because my program B would get severe troubles if its data-files were deleted by installaware upon uninstallation of this program (Program A).
I hope you can provide a bugfix for this!
