"Use manifest" applies a generic "standard" manifest and you can change very few options of it (mainly DPI awareness, etc.).
To apply a more carefully drafted manifest you should
uncheck that option and add the manifest file as a resource to your project ("Project Options->Resource"). You might also want to add it as a project's file in the Project Inspector so the tools know it's there.
Can't offer much more help; I left Windows behind, other than for testing and very few other things, quite some time ago.
