Force recognition of an installed OSAX?

I am working on an AppleScript Studio application that installs an OSAX. The problem is that the first time it is run it seems that the OSAX commands are not recognized. Is there any way to force the system to recognizes this newly installed OSAX? Failing that, is there a way to script the applescript studio application to quit and relaunch? The former would be much better, though.

Thanks!

There was a magical apple-event, but I ignore if it does still work:

try
     «event ascrgdut»
end try

This event should force a “rebuild” and “recognizion” of scripting additions.
