The Logger and Log Viewer utilities are automatically installed on any computer when you install a Logger enabled component.

Automatic means the Logger starts when the computer starts.

Manual means you must start the Logger from the System Services utility in the Windows Control Panel.
You can also customize which messages you want to log with the Log Flag Editor. For more information, see Log Flag Editor.
Note: Always check logged messages before calling technical support.
