How to launch executable after installation (exe is delivered by .msm)

Question

I did everything as explained in tutorial, but my executable wasn't launched after product installation completed. There is a nuance that my executable is delivered with .msm module, so in .wxs file for .msi I do the following to launch application:

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Product>
    <!-- I omit here features and elements which are irrelevant to the question-->
    <Feature Id="Configurator" Display="hidden" Level="1">
        <MergeRef Id="MergeConfigurator"/>
    </Feature>
    <UI>
        <UIRef Id="WixUI_Minimal"/>
        <Publish Dialog="ExitDialog" Control="Finish" Event="DoAction"
                 Value="LaunchConfigurator">WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1 and NOT Installed</Publish>
    </UI>
    <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="!(loc.ExitDlgCheckBoxText)" />
    <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOX" Value="1"/>
    <Property Id="WixShellExecTarget" Value="[#SystemConfigurator.exe.81c0fa8f-9a8e-49d8-9dc2-ce01ca163146]" />
    <CustomAction Id="LaunchConfigurator" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" />
</Product>
<Fragment>
    <DirectoryRef Id="TARGETDIR">
        <Merge Id="MergeConfigurator" SourceFile="$(var.MergeModulesPath)\ConfiguratorSetup_$(var.Platform).msm" DiskId="1" Language="1033"/>
    </DirectoryRef>
</Fragment>
</Wix>

For the property with Id=WixShellExecTarget I have tried to pass value both with and without GUID (this is Package/@Id of .msm with my executable). I opened my .msi with Orca and saw the exact ID of my executable (it's SystemConfigurator.exe.81c0fa8f-9a8e-49d8-9dc2-ce01ca163146, that's why I pass this very value).

But what it's wrong?

I logged installation process using /l*v option, and there is a portion from log:

Answer 1

Error 2715 means that the file key you're using isn't actually in the file table. Assuming it's referring to SystemConfigurator.exe.81c0fa8f-9a8e-49d8-9dc2-ce01ca163146 I would open the MSI file with Orca and see if that is the correct value AND keep in mind that Windows Installer proiperties are case-sensitive so if if it really is upper-case then use upper case. Make sure it really is a dash too, and not an underscore.
