I can visualize many beginners doing this as a first en.wikipedia.org/.../Hello_world_program the poor sods are not going to get an error message, the code will just hang.
I know why, but consider it bad that you get a hang, not an error message, especially when you feebly try do run Keil for the first time. Yes Please read the manual should cover it, but did you Please read the manual the first time you started C?

If this is directed at me:
No Erik, it most certainly is not; and unreserved appologies to you for causing you to think it was. It is very doubtful that any embedded developer has never forgotten the point you raise; I know I have!
The one who my post was intended for almost certainly knows the one who it was intended for.
I'll make a real big exception here and respond to point out the obvious: I don't care what you post, you are welcome to continue to. Feel free, the weekend is long. I'll be entertained. Go for it!
I don't care what you post
LOL. I just wonder if any support teams say the same of your bug reports.
