Need to add third party prerequisite after checking registry entry

[HarshSuman82]

I need to add a third-party prerequisite after checking registry entry. If entry is already present then custom action should not execute but it installing every time even registry is already present.

Please find the code below. Please let me know if I am missing anything.

        <Property Id="WVRTINSTALLED">

  <RegistrySearch Id="WVRTInstalled" Root="HKLM" Key="SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}" Name="EBWebView" Type="raw" Win64="yes" />

</Property>

<CustomAction Id='DownloadAndInvokeBootstrapper' Directory="INSTALLFOLDER"
              Execute="deferred" ExeCommand='powershell.exe -windowstyle hidden Invoke-WebRequest -Uri "https://go.microsoft.com/fwlink/p/?LinkId=2124703" -OutFile "$env:TEMP\MicrosoftEdgeWebview2Setup.exe" ; &amp; $env:TEMP\MicrosoftEdgeWebview2Setup.exe /install'
              Return='check'/>

<InstallExecuteSequence>
  <Custom Action='DownloadAndInvokeBootstrapper' Before='InstallFinalize'>
    <![CDATA[NOT(REMOVE OR WVRTINSTALLED)]]>
  </Custom>
</InstallExecuteSequence>
