Admin and installing

I want make an installer that installs updates during the startup of windows. Basically I will distribute the updater manually.

My problem is that some computers are running NT4.0 and some are running XP. Is there anyway to install programs when the normal user logs in? I know in XP it is possible to enter the admin pass during install. But how do i do this in NT 4.0?

Thank you,

The only way I can imagine it to work, is to launch the setup program from another program, using an API function like CreateProcessAsUser. You have to check that it is NT or XP first, because this API function is not available on Win9x or ME.

thank you, this solves my problem.
