Burn should detect when elevated process isn't actually elevated

[barnson]

• Describe the scenario and benefits that the feature supports.

Today, a standard user running without UAC can launch the "elevated" process just fine but it immediately fails trying to do something that requires admin privs.

• Describe how you're accomplishing the feature today (if possible).

Launch conditions.

• Describe what you'd like the new feature to do.

The elevated process should detect when it doesn't have elevated privileges and fail with a meaningful message.

Is this issue just about getting a better error message into the bundle's log? Or is it also supposed update the built-in BA's to show the error message?

[barnson]

The former. It's an extreme edge case (IT software that fakes elevation).
