It would be really really nice if you could merge a registry file into the installer at compile time. We have a .NET com class for which we generate a .reg file during the compile process. The installer is then compiled from the cli during the same build process. The issue is that when the details in the reg file change the old values need to be deleted from the installer and the file re-imported. It would be much nicer if we could specify that it pulled in the keys/values from a specified reg file when compiling.
