No "log to file" saved

I am using the free version 9.4 of Kiwi Syslog.  I have it setup to "log to file" D:\Program Files (x86)\Syslogd\Logs\SyslogCatchAll-%DateISO.txt

The problem i am seeing now is that when I go to the location where the log file should be saved:

D:\Program Files (x86)\Syslogd\Logs\

I can only see log files for those date that I launched the Kiwi Syslog Server application.  I thought with that setting, regardless if I launch the Kiwi Syslog Server application or not, the log file should still be collected and saved.

Anyone get any idea?
