Objective
To make a minor change to the appearance of the application and then create Version 2 to install the changed application.
What is a New Version?
A new version is created by copying the original version. The new version will contain all the components installed by the original version. The Windows Installer will process a Version upgrade as a full installation. If an earlier version is located on the target system, the Windows Installer will un-install the older version before installing the new version.
Version or Patch Upgrade?
The main advantage of a Patch is it is much smaller and therefore more easily, and more quickly, installed. A Patch only installs changes. A Patch must detect an install with the same GUID. There is more information on patches in this guide.
To achieve this objective, complete the following:
Step 1. Set DLL Version
Step 2. Enhance the Application
Step 3. Create Version 2 Package
Step 4. Install Version 2
