A power failure along with a battery failure *could* result in file corruption, NOT deletion.
Deletion requires: - an automated system (anti-virus for example) to explicitly delta the file - a user explicitly deleting the file - reinstallation of the OS - system recovery (maybe) I would not worry so much about the 4D application so much as the customer's data and structure files. The application can be reinstalled in a few minutes, AND (even on windows) I believe that the various preferences and license will be intact. If these are NOT intact, then likely they reinstalled the OS, or did some sort of system recovery to a very old state before 4D was installed.
