Need help overriding IIS App Pool and Site settings using WiX script

[rubymehto-allscripts]

Hello Team,

I’m trying to override the following IIS settings through a WiX script:

1. Idle Time-out: 0 (App Pool)
2. Idle Time-out Action: Suspend (App Pool)
3. Start Mode: AlwaysRunning (App Pool)
4. Preload Enabled: True (Site)

I’ve created a WiX script that successfully creates the App Pool and website and applies some custom settings. However, only the Idle Time-out value is being updated, the other settings remain (which provide as custom action) at their default values.

Could you please advise how to achieve this?
Below is my current WiX script for reference.
