RUNTIME WIN32 OR 64

I have developped an App in matlab 2015b installed in a win32 machine. Now, I'd like to send it to a client who has not matlab and works with a machine with win64. Which runtime do I have to send him.32 or 64 bits?

Send the 32 bit one. MS Windows win64 can execute 32 bit executables.
