Hi again.
As i also wrote in a post yesterday, I am also totally 100% for making it a service and can only agree with Linkster & Co.
But maybe you could combine both things.
You can check for Administrator rights or for the Username to
be "Administrator" before going on installing as a service.
As far as i remember its needed anyway to install anything
important like services and drivers. So i dont really see why
those "angry Admins" as you called them should have any
problems.
Offcause if they run all accounts with "Admins" rights,
But then they should look for a new job.....
