[wix-users] Run Burn Boostrapper or the MBA Elevated

[Sean Hall]

The old bootstrapper is a bundle that's already installed, right?  So it
should be in the package cache, which is a secure location for
ApprovedExeForElevation.  I'm not saying that it's not a pain to do it this
way, but it is possible to manually launch the old bootstrapper elevated
without showing multiple UAC prompts.

<ApprovedExeForElevation Id="PreviousVersion"
Key="SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{PREV-BUNDLE-ID}"
Value="BundleCachePath" />

Engine.LaunchApprovedExe(hWnd, L"PreviousVersion", L"/repair", 0)
