The MSI database is read-only. You can add information to the in memory copy but it is, of course, discarded when the install is complete. IIRC, the Windows Installer does not let you modify the stuff read-only from the database. I think that's just a restriction they enforce.
Why? You'd have to ask the Windows Installer team.
