[wix-users] UAC Admin permisions

Sat Mar 19 12:05:07 PDT 2016

Ronny,

Good to know that it works... Yes, It creates a second instance of the
setup msi if it is not elevated.

If you have a look at the code I have created a property ElevatedFromCA.
You can add this property to your WIX code and check for this property to
hide the exit page. Check the InstallUISequence for that page.
Regards,
Kaveesh
