Installing Edge Webview2 Runtime via Wix Bootstrapper

I am trying to install Edge Webview2 Runtime via a Wix Bootstrapper using the following code:

            <!-- Microsoft Edge Webview2 Runtime -->
            <ExePackage
                Id="MicrosoftEdgeWebview2"
                DisplayName="Microsoft Edge Webview2 Runtime"
                Compressed="no"
                Cache="no"
                PerMachine="yes"
                Vital ="yes"
                Permanent ="yes"
                InstallCommand="/silent /install"
                UninstallCommand="/silent /uninstall"
                Name="MicrosoftEdgeWebview2Setup.exe"
                DetectCondition="MicrosoftEdgeWebview2CurrentVersion64 >= MicrosoftEdgeWebview2MinimumVersion"
                SourceFile="MicrosoftEdgeWebview2Setup.exe">
                <Payload SourceFile="MicrosoftEdgeWebview2Setup.exe"/>
            </ExePackage>

I have placed MicrosoftEdgeWebview2Setup.exe in the Wix Bootstrapper Project. My code builds okay and I have verified that MicrosoftEdgeWebview2Setup.exe is being included in the final executable by opening it in 7zip.

The problem occurs when I try installing the executable. When it gets to the Edge Webview2 Runtime, a dialog box opens asking to locate Webview2Setup.exe. This is not the desired behavior as I have packaged MicrosoftEdgeWebview2Setup.exe in the Wix project. Am I doing anything wrong here?

[Note: I cannot package Edge Webview2 Runtime as a RemotePayload because the certificate details are being changed between versions.]
