and noticed that when I was logged in as a standard user (not admin) it does not trigger a UAC prompt and allows me to install the application even though I am not running elevated. Typically a setup file in such a circumstance would trigger a UAC prompt with the message: "To continue, type and administrator password and then click Yes."
I looked at all the security settings although I could not work out what was set to turn off UAC for the setup file. Is it common, and what do I look for to determine if a setup file is designed to get around UAC? Could it be a simple manifest issue?
