deployment of add-ins & registry

Question

hi, i have recently finished my first add-in for ms word( written in c# ), but i couldnt deploy it to a target machine. setup package seems ok, it unpacks in target machine smoothly, but no registiration is performed, so it does not work when word is opened. is there anything i have to do for dll files to be registered directly when setup files are unpacked in target machine? thanks a lot.
