[wix-users] Deferred Custom Action

[Giuseppe Grilli]

Hello everybody,
I've a Custom Action which requires to be executed with elevated privileges: I've set it to be executed as "deferred" and is executed after InstallInitialize.
But I need its result while in InstallUISequence to interrupt the setup in case of negative response of CA.
Is it possible to achieve this scenario? Which is the right approach to solve this problem? 
Of course, I do not want to execute the .msi package with admin rights.

Regards

Giuseppe
