Well first of all deploying the code is pushing the arrow, building is found under build specifications then right click build then run as startup, building the code puts it on the C-rio permanently(or at least till you build another). If he is running the code from robot main by clicking the arrow then he needs to open the DS while main is running to get the code to run on the c-rio.Another thing that could cause this is if he is building the code and not running it as startup.
If you describe the exact steps you are following i can help you more.
