how to crete setup for upgrade

[Mukund Patel]

Hi,

I want to implement my existing setup for newer version. There are few more
new files. If previous appllication already installed in a machine new setup
will install only new files and if it is first time installation set will
install whole application.

How to implement this feature in my setup?

Thanks

If you're adding new files, I'd suggest that this is a new product (fixes
would replace existing files, not add new ones). The simplest thing that
will do both those things you asked is a major upgrade. It depends on what
tool you're using (InstallShield, Wise, ActiveInstall, Visual Studio etc) to
build the setup exactly how you create one. Change the ProductCode,
PackageCode and increment ProductVersion, and populate the Upgrade table.
Then the single MSI file will replace the existing product if it's there,
otherwise it will behave like a first time install of the product.
