If you're authoring a Windows Installer (MSI) application, and updating it using MSPs, then Windows Installer has built-in support for exactly your scenario: - check out User Account Control (UAC) Patching.

It works basically like this:

• When you author the original MSI, You generate a certificate, and you put its public key (or something like that) in the MSI.
• The target machine's admin installs the MSI on the machine.
• You author an update (MSP), and sign it with the certificate.
• Any user on the target machine can now install the update - Windows Installer will validate the certificate against the public key in the original MSI, and agree to install if so. I don't think you'll get a UAC prompt at all, though I'm not sure.
