Applies To: • CitectSCADA 5.xx • CitectHMI 5.xx Summary: When I restart my computer and CitectSCADA attempts to run automatically on startup (either as a service, or by a shortcut in the startup folder) CitectSCADA fails to start, and displays the error 'Software Protection Failure' or 'Cannot Find Serial Drivers'.

To work around this limitation in Windows XP, you can delay the startup of CitectSCADA by setting the following parameter in the Citect.ini file: [GENERAL] StartDelay=120!

Delay Citect startup by 2 minutes The exact value required may vary from computer to computer, but normally 2 to 3 minutes is sufficient to allow the drivers to load. See also Q3963 for a way to start Sentinel immediately on Windows startup so a Citect start delay is not needed.
