Groxzzl/StrixMacroAss ? reverse-engineered prompt

Build me a simple Windows macro app in C with a small GUI that lets the user enter a license key, click Activate, and then run a macro. It should feel like a basic desktop tool, with a clean window, a button to start and stop the macro, and a status message showing whether activation worked.

I want the app to talk to a remote validation endpoint with the key and a machine ID, then unlock the macro if the server says it is valid. If the request fails, show a helpful error instead of crashing. Keep the code straightforward and split into a few source files if that makes it easier to manage.

Use the existing image for the main UI if it helps, and keep the whole thing lightweight and easy to run on Windows. Look up current docs online if you need to.
