Cannot run exe from asp.net

I have tried to read https://www.daniweb.com/programming/web-development/threads/386380/cannot-run-exe-files-in-asp-net-application but still lost in trying to achieve something. I installed the latest .net framework, and IIS on the latest updated windows 11. I wish to achieve the following:
Have a webpage with a button, when pressed, it will launch a webpage that runs a server side exe (eg, notepad.exe or ribbons.scr), while at the same time run the same exe on the local client pc.
For my attached source files, i dont know why the index.cshtml doesnt show a button. Also disappointingly the notepad.exe did not run even when i set it to have security permissions so let everyone have all rights. im a little confused why there were 2 web.config files, and the IIS interface didnt seem to match the web.config settings, and also i dont understand why the visual studio code will launch the site with a certain port number, while your previous discussion 13 years ago suggested to use the session state to run at a different port.
Thank you for reading!
