InstallShield, update files that were modified

I'm using InstallShield in order to create an installer/updater for an application (Basic MSI). I have installed an application (version 1) with the installer and then manually modified some files. The problem is that when I upgraded this application to version 2 with a new installer, it didn't overwrite these manually modified files. I got this message in the installation log file:

Won't Overwrite; Won't patch; Existing file is unversioned but modified

For properly overwritten files I get this in the log file:

Overwrite; Won't patch; Existing file is unversioned and unmodified - hash doesn't match source file

Question: is it possible to automatically overwrite these manually modified files during the upgrade process? Is there a setting in InstallShield that lets me do this?

This happens because the file versioning rules prevent Windows Installer from overwriting the files. Basically, when modifying your source files you should also increase their version (if possible).

You can use the RemoveFile table. You can access this from the DIRECT EDITOR of Installshield IDE. Configure RemoveFile Table to remove the modified files.
