How does the Chrome Setup.exe work under the hood on a Windows PC?

Chrome has a very smooth installation process and I would like to imitate this setup behavior in my own 开发者_开发百科application.

How can I leverage this in .NET? What are the limitations?

Is there any comparable Microsoft technology in the .NET Framework? (or comparable to it)

The installer is an open source project called Omaha, with a high-level overview here.

Ultimately, Chrome installs to the current user's directory (i.e. C:\Users) on Windows Vista/7, so it can avoid the UAC prompt. I'm not sure if this is how Omaha works, or if that's just how Google decided to install Chrome.
