If you organise your code into assemblies then you need to only
replace the modified assembly. For that to work you will need to
organise your code into separate classses for different business and
database functions and then you can move those class files into a
class library project and compilt to DLL. Suppose you will have many
DLLs, then you only need to replace the DLL which was modified by you
in your recent change to the code.

Also if you think yours is a small and simple application made up of
only one exe and some supporting files, why you don't just overwrite
the old exe and other files with the new files. Why you want to run
the setup again?

Also worth checking out is something called ClickOnce Deployment -

So there are many solutions to your problem. If you give more info
about the structure about your application, what is installed on
user's machine by the setup and things like that I can try to help you
more.
