How to install the application using ClickOnce using WiX?

I am writing a WiX installer for an application that has been deployed previously using ClickOnce.

I would like to determine if the application is installed on the client computer and abort the MSI installation. I searched for similar questions in Stack Overflow, but couldn't find a way to do this.

If I can find the path or any registry key that tells me where the application was installed, I can abort the MSI installation using the condition.

Using the answer for this question , I was able to get somewhere. ClickOnce shortcuts are files with the .appref-ms extension . This is the code I'm using:

<Property Id="APP_CLICKONCE_INSTALLED">
    <DirectorySearch Id="dirSearch.APP.CLICKONCE" AssignToProperty="yes" Path="[StartMenuFolder]" Depth="2">
    <FileSearch Id="fileSearch.APP.CLICKONCE" Name="APP.appref-ms" />
    </DirectorySearch>
</Property>

<Condition Message="App is already installed. Please uninstall it then re-run this setup.">
    <![CDATA[APP_CLICKONCE_INSTALLED = "" OR INSTALLED]]>
</Condition>

StartMenuFolder AllUsers, . .

perUser StartMenuFolder ( perMachine):

<Package InstallerVersion="200" Compressed="yes" InstallScope="perUser" />
