In this post I'm going to look at Windows Manifest Files, what they do, why we need them and how to use them in Delphi and FinalBuilder. We often get asked questions about uac prompts, high dpi settings, windows themes etc when compiling Delphi & C++Builder projects in FinalBuilder. In this post we'll dissect windows manifest files, and look at how the project settings in Rad Studio interact with the manifest file, and why you should use a custom manifest file.
