Wix Check if Application Initialization is installed on 2008R2

I need to check if Application Initialization is installed on a 2008R2 Server.

The app is not installed as a feature, it is an IIS Module that I downloaded from the following link.

The problem I'm having is where does the folders actually get placed to be able to perform a search in my WiX project to see if they exist or not.

TLDR:

Look for the Version value in HKLM\SOFTWARE\Microsoft\IIS Extensions\Application Initilaization. Current version is 7.1.1636.0.

Full answer:

Since this is a MSI installation package, you can open it using Orca and search for any registry key being created.

Then in Orca, you open the Registry table and find the row with Registry=reg8BD5741527F144C70BDB7B0134BC7B84. In it, you will find the Key where the value will be created, the Name of it and the Value.

This way, you can easily perform a registry search and evaluate if the module is installed.

EDIT

To perform a search during launch and verify if the module is installed, add the following code:

<Property Id="MODULEINSTALLED">
    <RegistrySearch Id="IsModuleInstalled"
                    Root="HKLM"
                    Key="SOFTWARE\Microsoft\IIS Extensions\Application Initilaization"
             Name="Version"
                    Type="raw" />
</Property>

Then use the property in a condition:

<Condition Message="This application requires Application Initialization module. Please install the Application Initialization module then run this installer again.">
    <![CDATA[Installed OR MODULEINSTALLED]]>
</Condition>
