Before Close Application Open A Site

hi
i want when user close the application (when click on close) or kill the application process In any case,application before close start a line of code:
ExecShell "Open" "http://Google.Com"
iIs it possible?

i think i most use from:

  Function .onInstSuccess

 ExecShell "Open" "http://Google.Com"

FunctionEnd

this method is true?

Forcing the user to open a URL is not cool. The Finish page already has URL support, use MUI_FINISHPAGE_LINK.

If you are using RequestExecutionLevel Admin then I recommend that you don't open a URL at all, it can launch the browser elevated and/or as the wrong user...
