How to putting update for my program?

BillWoodruff is correct - clickOnce deployment is generally created to solve this more complex issues...but is has limits you should read about.

Here's the general overview documentation (sorry there's no 30-second way to tell you how to get everything in your project to work with clickOnce, but this should help):

generally, pushing updates to installed applications(like a winforms or wpf app) requires admin rights and deployment of dependencies (i.e. other libraries you are calling in your app for controls, reporting, data access, etc.). while this is not always the case, it often is.

clickOnce allows you to deploy to users via a URL and the program can be set to check a URL for updates (and to update itself). this deployment type installs the program using the security context of whomever is initiating the clickOnce deployment - generally a regular user. clickOnce gets around some of these normal non-administrative permission limitations by installing to the user's profile area - so the app gets installed per-user - NOT per computer. Note that registry access may be limited as well, etc. i.e. you can't do administrative things from a clickOnce app running as a normal user - it is not magical and will not grant additional rights to the user automatically.

the link i sent you has a comparison table that explains some of what i'm mentioning here.

finally, if you are set on some kind of updating without clickOnce note that it will require a web service/web server to deliver & host updates...some kind of windows service run with admin rights on the target computer that can check for updates and install them with administrative rights (if that's required) and some notification system built into the app to know when to check and when to prompt (i've done this with database tables that get checked on demand or at startup).
