Desenvolver um Software

I have an online game, and every time I need to edit the client, and every time the players need to download the client to play again updated! I wanted a launcher with auto update if the player does not have the latest update, he can not play, and have to refresh, this launcher I need something to replace the files (update the client automatically) every time I do something new in the launcher like a good clean and beautiful Designer, and add an iframe to the news updates!
