It depends on what installation technology and toolbox you are using...
Aren't the standard way is good enough: when you run the same installer when the product is already installed, the user is prompted to uninstall? It it's uninstalled, the user can install the newer version.

Usually if you set an high version number of the same product (setup version), previous version is automatically removed.

It depends. It's possible because, essentially, the removal of older version is based on the copy of the installer automatically preserved in the installation. Only that installer "knows" how to uninstall the previous version.

So you need to do patch update right ? you can use MSI (which is with Visual studio, now it is replaced with InstallShield Limited Edition) or Inno setup[^] is also a good one. here you can customize your patch upgrade with different scripts

You probably need to look into the use of ClickOnce technology[^].

Obviously someone did not like your answer. Nevertheless it is perfectly valid, given what OP describes in this "question".
