No. This is a definite no no from security. Never try to have something
going on without the user creating some interaction to cause it. Trying to
run an executable is a very big no no fromthe browser's perspective and many
will try to shut it down unless the user says otherwise Remember, the act of
clicking a link and then responding to the save/run dialog is a very good
thing and many users would really freak if an exe just started running by
itself and would probably be afraid that your site is doing something
illegal to their systems.
Hope this helps,
