When you made a working software, next step is called distributing. Which mostly means putting all your software files into a distribute package. For this you have to choose distribute system (my favorite is NSIS ).

It is the job of installer to detect whenever software is already installed and offer Repair or Uninstall option. And it should be very basic thing supported by distribute system (read - it will be very easy to do).
