create setup that allows updates to be downloaded

[steve_rm]

Hello,

My customer wants to be able to update the program and download only the updates from the server.

The customer wants to install the application and then download updates when they are available. And install them without having to reinstall the program.

I started using the clickonce which works ok for this situation. However, the customer did not like this as it always installs in the default documents and setting directory, and the updates that are downloaded as the same size as the initial program size. As the updates are only small the customer only wants to download those updates so it will be quick to download and quick to install.

Is there another method to be able to do this, maybe some free third party, or can you configure the MSI to do this.

The customer would like something like norton anti-virus where only the updates are installed only.

Many thanks in advance,

Steve

That is not a the function of an INSTALLER. That is an function of your application. Once installed you would NEVER want the installer to update itself. How would you know if it would work the next time???
