There are two instances of one application name in the Add/Remove programs dialog box if you install two packages that are based on the same template

If you install two packages that are based on the same template on one computer, there are two instances of the application name in the Add/Remove Programs dialog box. If you install these two packages to the same file location, the second installation overwrites the first installation.

The Package Wizard that is included in Microsoft Office Access 2003 Developer Extensions (ADE) does not create patches for installations. When a new package is created, a new product code is created. Therefore, Microsoft Windows Installer treats the new package as a new product.

This behavior is by design.

Steps to Reproduce the Behavior

1. Create a package by using the Package Wizard.
2. Install the package on a test computer.
3. Make a modification (for example, modify a label control caption), and then try to repackage the application.
4. Install the updated package on the test computer.
