I have a confusion related to ClickOnce application development.

I have a windows forms applications. what if I only replace the MyApp.exe and related DLL files in the program directory instead of building the project with ClickOnce? will it work. what is the advantage of ClickOnce.

You can do this, providing the user has permissions to write to this location. If you use ClickOnce, once the application has been initially installed a user doesn't need to have elevated permissions for an upgrade.

I concur. If it is a program used by a very limited amount of users, yes, this would be the better option. But, with any major enterprise application, you would need to use ClickOnce

Arjay and Hannes, thanks for your replies.

Can I make an installer with ClickOnce which updates my software to newer version without uninstalling the older version.

Limitation: assume my machine where the software will be installer has not internet access from where to download the assemblies.

Have you read the documentation on ClickOnce deployment?

Yes, according to Microsoft,

With ClickOnce deployment, you publish the application to a centralized location and the user installs or runs the application from that location.

I don't have a centralized location and the client machine also don't have internet access so the question of implementing Automatic Updates does not arise here. I can only work with windows installers here.

Can a windows installer be modified in such a way that it doesn't ask to uninstall the previous application and installs the latest version on it.
