Delta Product

You create a delta product, if one or more previously packaged products are required for the correct installation of the product you are packaging.

Tthe steps to create a delta product are as follows:

1. From the Install Previously Created Products dialog install the previously archived product, that is, the product required for the proper installation of the product you are packaging.
2. When prompted for the type of product to generate, select Delta product.
3. Install the actual product you are packaging and finish executing the steps described under Using the Automatic Method.

Example:

Suppose you want to package an emulation program to be installed on the Packaging Computer only if an SNA layer program is installed. However, you do not want to package and distribute the SNA layer together with the emulation program because you want to be able to update each product independently.

First, you install the SNA layer program from the product archive. When prompted which type of product to generate, select delta product and then install the emulation program. You are creating a delta product for the emulation program. The Packager records into the emulation package only the changes from the emulation program, and not the changes from the SNA layer program.

Installation Consideration:

If the Installer must install a delta product, but the required base product is not installed on the target computer, the Installer aborts the installation and displays an error message. You must enter the dependency on another product manually in the section InternalDependence in the info.sxp archive file.
