This message appears in DocShuttle Dictator when the "Use Olympus file header information" checkbox is checked on the "Import" tab of the Settings window. This setting requires proper DLL files to be installed from the Olympus DSSPlayer software. This setting is supported with Olympus DS-4000, DS-2300 and DS-3300 recorders. If the Olympus DSSPlayer software is not installed or the correct version is not installed, this message may appear.
One solution to this error message is to uncheck the "Use Olympus file header information" checkbox.
