How can I use the new ability to launch an elevated process after installation is complete?

Question

The current set of samples on how to use the new opportunity to run the increased process through the engine is very scarce if it exists in everything. From the WIP documents and schema, I see that I need at least the following:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:bal="http://schemas.microsoft.com/wix/BalExtension">
    <Bundle Name="..." Version="1.0.0.0" Manufacturer="..." UpgradeCode="*">
      <BootstrapperApplicationRef 
           Id="WixStandardBootstrapperApplication.RtfLicense">
        <bal:WixStandardBootstrapperApplication 
           LaunchTargetElevatedId="LaunchElevatedInstallProc" 
           LaunchArguments="/myarg=1" 
           LicenseFile="license.rtf" />
      </BootstrapperApplicationRef>

      <ApprovedExeForElevation 
          Id="LaunchElevatedInstallProc" 
          Key="SOFTWARE\Company\Product" 
          Value="PathToExeDeliveredByMSI" />

      <Chain>
        <MsiPackage SourceFile="Setup.msi" Compressed="yes" />
      </Chain>
   </Bundle>
 </Wix>

The attribute Key <ApprovedExeForElevation>makes sense; this is the registry path to the entry that was created in my msi. The attribute Valueis the ValueName in the registry that I created, containing the path to the .exe that I set in my installation:

  <Component Id="Comp_Client_Service.exe" Guid="PUT-GUID-HERE">
    <File Id="my.exe" Name="my.exe" Source="my.exe" KeyPath="yes" />
    <RegistryValue 
         Root="HKLM" 
         Key="SOFTWARE\Company\Product" 
         Name="PathToExeDeliveredByMSI" 
         Value="[INSTALLFOLDER]my.exe" 
         Type="string"/>
  </Component>

However, this does not seem to work. My .exe never starts, and the .log file does not provide any information that it even tries to run it.

What is this code missing?

'LaunchArguments' '/s'

Answer 1

documentation TargetPath WixStandardBootstrapperApplication . WixStdBA exe , - , .

Id of the target ApprovedExeForElevation element.
If set with LaunchTarget, WixStdBA will launch the application
through the Engine LaunchApprovedExe method instead of through ShellExecute.

Success LaunchButton .
