[wix-users] UAC Admin permisions

[Phil Wilson]

Custom actions in the UI sequence aren't elevated, so the answer is always
to elevate the MSI when you start it, and an elevated executable will work
as long as you do a CreateProcess run of the MSI (not a shell run) so that
elevation is transferred.  The assumption is that installs require elevation
only when they are actually altering the system, not when collecting input
in the UI sequence. 

So doing this will always require elevation - there's no getting away from
that, so elevate the entire MSI install, or shell out an executable custom
action from the UI sequence that will request elevation and populate a file
your UI custom action could read, something like that anyway.

Just checking if you have resolved this... If yes how?
