[wix-users] Is it possible to launch a custom Burn UI as administrator?

[Nir Bar]

You need to build WiX from source and change burn.exe manifest to require elevation.
Then copy burn.exe to WiX installation folder, usually "C:\Program Files (x86)\WiX Toolset v3.11\bin\x86\burn.exe"
Do keep a backup of the original burn.exe should you require it in the future.
