Issue reading EventLog entries for Standard user on Windows 7

I am trying to read the Windows Security Event log by notification.

Below is sample line of code, but when I run it on Windows 7 with a standard user I get an Exception:

EventLog _eventlog = new EventLog("Security"); //Monitor on the Security events 
_eventlog.EntryWritten += new EntryWrittenEventHandler(OnSecurityEventLogWritten);
_eventlog.EnableRisingEvents = True; // I get an exception at this line with a Windows 7 standard user

I am getting the exception saying Requested Registry is not allowed. I tried adding the user to the Event Log Readers Group but that did not help.

It's important to note that when I run this application with local admin rights it works fine.

My requirement is to get the notification when Windows Security events and written for a standard login user.
