System Event Log
The System Event Log is a Windows component that collects informational and error messages issued by Windows itself and other third-party software. Sandboxie issues some messages to the System Event Log. The messages are listed with a Source value of SbieDrv. To access the log and view messages, use the Event Viewer tool:
Windows Start Menu > Control Panel > Administrative Tools > Event Viewer
For more information about the System Event Log, see Event Viewer in Wikipedia.
If any Sandboxie messages are issued due to an error which prevents successful initialization, Sandboxie Control will display a flashing exclamation mark icon. Right-click the flashing icon and select Show Errors to view any related messages.
Messages From Sandboxie are not stored in the Windows Event Log, a workaround is available to store the logs in a flat file.
