You're running into https://github.com/wixtoolset/issues/issues/6349. In
v3, you'll have to poll the WixBundleElevated variable after calling
Engine.Elevate like the person in the thread you linked to earlier. Don't
do that in a callback from the engine like OnElevate, you'll just hang. If
you do it from a UI thread, make sure to process messages in that loop so
the UI remains responsive (Application.DoEvents in WinForms).
