MSI, UAC and Unidentified Publisher. How do I change the Unidentified Publisher?

Question

I am currently working on a MSI package for one of my application. It works well; however, before the installation starts, I get the expected UAC window asking me if I trust or not this program from the Unidentified Publisher. I am not concerned by UAC itself, but by the Unidentified Publisher. How do I change that? I've heard that I need a special certificate... If it is the case, where can I get it?

This is a pretty good reference to it...

Answer 2

You need a code signing certificate.

I use and recommend Comodo which charge as little as $179/year. This is a real bargain when compared to $499/year from Verisign
