+This sample demonstrates how to ensure that setup runs elevated UI.
+Normally MSI elevates the actual installation stage (InstallSequence) while leaving the UI interaction (InstallUISequence) unelevated. This sample shows how to elevate the whole round trip.
+Note: the ManagedUI gives you the best user experience as native UI does not allow full control over dialogs (the initial setup exit dialog needs to be closed manually).  
+Execute corresponding .cmd file to build desired msi. Then execute the .msi to start the installation.
