I'm not exactly sure what you're getting at here, but the EDITA1 value could
be passed to a custom action as [EDITA1] case-sensitive and your code could
change whatever original file name is to this new one. However that won't
help you because Windows Installer will see that the file that it installed
is no longer there and a repair will restore it, so you'll end up with
original and new files, and the new one won't be removed at an uninstall. In
general, I don't think you can do what you're trying to do, and I've never
seen an install that's asked me to supply a new file name.
