That was quite a session with ChatGPT and StackOverflow to hack this out. For the real name in the dll you need DependencyWalker. The dll will only be loaded at installation for something you can't do in InnoSetup. It's a good idea to compile the dll for x86. Turns out you can do this directly (getting the Build Number), but maybe it's useful for a case where you can't.
