we have created one custom action which run after install finalization .in that custom action we calling a powershell script . The purpose of this script is set application pool 4.5 with specific user and from that user we need to encrypt sensitive info for particular section.

Add-Type -assembly "Microsoft.PowerShell.Commands.Management.resources"
Add-Type -assembly "Microsoft.IIS.PowerShell.Framework"

$username = Get-Property -Name SERVICEUSER
$plainPassword = Get-Property -Name SERVICEPASS
$password = ConvertTo-SecureString $plainPassword -AsPlainText -Force

$cred = New-Object System.Management.Automation.PSCredential($username, $password)

Import-Module WebAdministration
Set-ItemProperty iis:\apppools\"Asp.net v4.5" -name processModel -value @{userName=$username;password=$plainPassword;identitytype=3}

# Registry entry for ProtectionPolicy access
if (Test-Path "HKLM:\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb") {
