Creating a patch using InstallShield 2008

Hello,

I would like to create a patch for my program. I have a simple window app for testing. Using VB 2005. I have created the application and then added the MSI basic project.

I then went to the project assistant and added the default settings. The project built, installed, and ran ok.

Now I have made some changes to my windows application. And I want to create a patch, not sure now to do this.

I have tried using the quick patch project and the design patch configuration. I am able to create the patch and install it, but it doesn't update the windows application to show the new changes.

Once I have my patch working, should I be able to give the patch.exe to the customer, and they should be able to install it without having to uninstall? The patch should be very small as it is just a few simple changes.

Many thanks for any help you can give me,

Steve
