[wix-users] UAC Admin permisions

[Ronny Eriksson]

Well to answer Kaveesh question, no i have not.
But I would like to find a way to just find the Sites and AppPools in the IIS without having to use the ServerManager object since you need to be admin to do the connection.
Unfortunaly, Phil, just retrieving data from that object requires Admin...

So firstly I'm looking for another way to solve it.
If not I might have to look in to doing something like u say.

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.

Hi Ronny,

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