We solved our problem using Windows Service. Our app will download the new msi, then call a WCF service, passing the path of the installer and the Service will install the new version without any problems because our service run under local account system and i think this is the only supported solution

You are requesting silent MSI installation therefore MSI will not display any UI - nor the UAC dialog.

Your parent process must already run with elevated privileges, or you must request elevation from Windows and use the privileges token to run new process.
