I haven’t used exerb but I think you may need to run a.exe from the  
command line. It sounds like you’re double clicking on it in Windows.

If I understand it correctly, you click on the file name, it opens a  
command window, prints “hello world” and exits the program, therefore  
closing the command window after that.

Cheers

Yes - and if this is happening, simply open a command window first, then  
launch your exe file from the command line - “ruby {name}.exe”. The  
command window should remain open upon program termination.
