I am trying to silently execute a PowerShell script from a WiX produced MSI.
However, anytime I run the installer PowerShell hangs. This in turn hangs the
installation process. PowerShell is running the script "properly" in that the
script is able to make changes to the system and no errors are reported.
Interestingly, if I kill the PowerShell process via Task Manager, the installer
cancels the installation and rolls back any changes.

My PowerShell Script
--------------------------------------------------------------------------------
# @param website The website under which the module should be compiled and
registered.
# @param name The name of the module to be registered.
# @param assembly The assembly name, version, culture and public key token to
be compiled.
# @param assemblyType The fully qualified assemebly type to be registered.
param([string]$website = "website", [string]$name = "name", [string]$assembly =
"assembly", [string]$assemblyType= "assemblyType")
import-module webadministration
add-webconfiguration /system.web/compilation/assemblies "IIS:\sites\$website"
-Value @{assembly="$assembly"}
new-webmanagedmodule -Name "$name" -Type "$assemblyType" -PSPath
"IIS:\sites\$website"

Wix Custom Action Contents : Attempt 1
My first attempt at this was to use the & special character to execute the
script
--------------------------------------------------------------------------------
<CustomAction Id="RegisterHttpModulePSCmd"
Property="RegisterHttpModulePowerShellProperty"
Value=""C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe"
&'C:\Program Files (x86)\My Company\Scripts\register-httpmodule.ps1'
-website 'Default Web Site' -name 'MyCustomModule' -assembly
'MyCompany.Product.Feature, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=xxxxxxxxxxxxxxxx' -assemblyType
'MyCompany.Product.Feature.MyModule'"
Execute="immediate" />
<CustomAction Id="RegisterHttpModulePowerShellProperty"
BinaryKey="WixCA"
DllEntry="CAQuietExec64"
Execute="deferred"
Return="check"
Impersonate="no" />
<InstallExecuteSequence>
<Custom Action="RegisterHttpModulePSCmd" After="CostFinalize">NOT
Installed</Custom>
<Custom Action="RegisterHttpModulePowerShellProperty"
After="InstallFiles">NOT Installed</Custom>
</InstallExecuteSequence>
--------------------------------------------------------------------------------
Wix Custom Action Contents : Attempt 2
My second attempt was to use the -File argument to execute the script.
--------------------------------------------------------------------------------
<CustomAction Id="RegisterHttpModulePSCmd"
Property="RegisterHttpModulePowerShellProperty"
Value=""C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe"
-NoLogo -NonInteractive -NoProfile -File "C:\Program Files (x86)\My
Company\Scripts\register-httpmodule.ps1" -website "Default Web
Site" -name "MyCustomModule" -assembly
"MyCompany.Product.Feature, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=xxxxxxxxxxxxxxxx" -assemblyType
"MyCompany.Product.Feature.MyModule""
Execute="immediate" />
<CustomAction Id="RegisterHttpModulePowerShellProperty"
BinaryKey="WixCA"
DllEntry="CAQuietExec64"
Execute="deferred"
Return="check"
Impersonate="no" />
<InstallExecuteSequence>
<Custom Action="RegisterHttpModulePSCmd" After="CostFinalize">NOT
Installed</Custom>
<Custom Action="RegisterHttpModulePowerShellProperty"
After="InstallFiles">NOT Installed</Custom>
</InstallExecuteSequence>
--------------------------------------------------------------------------------
Both approaches seem to work as they make modifications to the desired
web.config file, however, both approaches hang PowerShell and thus the
installer.
How do I silently execute a PowerShell script from Wix without hanging
PowerShell?
