The Generate File Hash Values property indicates whether you want to populate the MsiFileHash table for every unversioned file in your build.

- Yes—Populates the MsiFileHash table for every unversioned file in your build.

- No—Does not populate the MsiFileHash table. If you select No, InstallShield builds any entries that are found in the project's MsiFileHash table (populated using the Direct Editor).

If you have already populated the MsiFileHash table for a particular file, the build uses that information instead of generating the information at build time.
