Eric,

I'm not aware of how you could go about elevating the privileges of a  
running exe.

The way I do this is the vbs technique. While my application is  
running I download the update. I then launch the vbs file I mentioned  
in my previous and quit the application. The VBS file in turn launches  
another VBS  file using elevated privileges. This second VBS file  
waits for the main app to quit (watching the process ids), installs  
the updater files and then relaunches the main application.

The other option I see would be to write a small exe that has the  
embedded manifest and handles installation of files. Your main exe  
could launch this during the process.
