Had an issue where the updater application for a rack mount buffalo terastation iscsi edition would not seem to run. Checked that the download was not corrupt but each time it was started there was no splash screen or sign of the application searching for terastations as expected.
The issue – antivirus (in this caser sophos) was preventing the app running. Turning it off termporarily allowed the app to start and find the terastation. Update ran as expected and the terastation is running as hoped after the new software revision was rebooted.
So if the app doesn’t start – check your av first.
