This is a permissions problem - you should give the running user permission to read the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\EventLog

Alternaitvely you can bypas the CreateEventSource removing the need to access this registry key.

Both solutions are explained in more detail in the following thread - How do I create an Event Log source under Vista?.
