During the Challenge/Response procedure for a SafeGuard Enterprise Standalone Client (when loading the BAK file) "Error: Invalid BAK file" is displayed.
Known to apply to the following Sophos product(s) and version(s)
SafeGuard Management Center
All supported Operating Systems
What To Do
The error message will be displayed if:
- the BAK file itself has been damaged/corrupted
- the Policy Editor/SafeGuard Enterprise Database that was used to create the SGN Standalone Client Config package for the client machine has changed and therefore the BAK-file is signed with a different company certificate as the one currently used in the "new" policy editor (resp. SGN Database)
In this case, you have to perform a Challenge/Response from a Policy Editor that is connected to the SafeGuard Enterprise Database that was originally used.
